Patran Interface to SAMCEF Preference Guide Purpose

Purpose MSC Patran comprises a suite of products written and maintained by MSC.Software Corporation. The core of the product suite is MSC Patran, a finite element analysis pre and postprocessor. MSC Patran also includes several optional products such as advanced postprocessing programs, tightly coupled solvers, and interfaces to third party solvers. This document describes one of these interfaces. For more information on the MSC Patran suite of products, see the MSC Patran User’s Guide. The MSC Patran SAMCEF Application Preference provides a communication link between MSC Patran and SAMCEF. It also provides customization of certain features that can be activated simply by selecting SAMCEF as the analysis code preference in MSC Patran. MSC Patran SAMCEF is integrated into MSC Patran. The casual user will never need to be aware that separate programs are being used. For the expert user, there are three main components of MSC Patran SAMCEF: several PCL files to provide the customization of MSC Patran for SAMCEF, PAT3SAM to convert model data from the MSC Patran database into the analysis code input file, and SAMPAT3 to translate results and/or model data from the analysis code results file into the MSC Patran database. Selecting SAMCEF as the analysis code under the “Analysis Preference” menu customizes MSC Patran in five main areas: 1. Material Library 1. Element Library 1. Loads and Boundary Conditions 1. MPCs 1. Analysis forms PAT3SAM translates model data directly from the MSC Patran database into the analysis code-specific input file format. This translation must have direct access to the originating MSC Patran database. The program name indicates the direction of translation: from MSC Patran to SAMCEF. SAMPAT3 translates results and/or model data from the analysis code-specific results file into the MSC Patran database. This program can be run so that the data is loaded directly into the MSC Patran database, or if incompatible computer platforms are being used, an intermediate file can be created. The program name indicates the direction of translation: from SAMCEF to MSC Patran.

The MSC Patran SAMCEF Application Preference is written and maintained by SAMTECH

Patran Interface to SAMCEF Preference Guide What is Included with this Product?

What is Included with this Product? The MSC Patran SAMCEF product include the following items: 1. PCL command and library files which add all the MSC Patran SAMCEF customization definitions into MSC Patran. This file is named SAMCEF.plb. 2. The executable programs PAT3SAM and SAMPAT3 which perform the forward and results translation of data. Although these programs are separate executables, they are run from within MSC Patran and are transparent to the user. 3. Script files are also included to drive the programs in item 2. These script files are started by MSC Patran and control the running of the programs in MSC Patran SAMCEF. 4. The MSC Patran SAMCEF Preference Guide is included as part of the product.

Main Index

Chapter 1: Overview 5 MSC Patran SAMCEF Integration with MSC Patran

MSC Patran SAMCEF Integration with MSC Patran Several diagrams are shown below to indicate how these files and programs fit into the MSC Patran environment. In some cases, site customization of some of these files is indicated. Please see the Patran Installation and Operations Guide for more information on this topic. Figure 1-1 shows the process of running an analysis. The SAMCEF.plb library defines the various Execution Parameters, Solution Type, Solution Parameter, Specific Options, Select Loads Cases and Output Request forms called by the Analysis form. When the Apply button is selected on the Analyze form, a.jba file is created, and the script samcefSubmit is started. This script may need to be modified for your site installation. The script, in turn, starts the PAT3SAM forward translation. MSC Patran operation is suspended at this time. PAT3SAM reads data from the database and creates a BACON input file, or Banque file. BACON and then analysis modules are executed in series after successful translation, if the user has requested that action. A message file is created to record any translation messages

whether model or results data is to be read. A process is then spawned to start the SAMPAT3 results translation. The MSC Patran database is closed while this translation occurs. A message file is created to record any translation messages. SAMPAT3 reads the data from the SAMCEF results file. If SAMPAT3 can find the desired database, the results will be loaded directly into it. If, however, it cannot find the database SAMPAT3 will create a new MSC Patran model database before loading the results. SAMPAT3 is also used to create a “query” file, used when recovering a summary of available results. Then, the user may also request generation of a MSC Patran 2.4 Neutral (topology) file.

Patran Interface to SAMCEF Preference Guide Introduction to Building a Model

Introduction to Building a Model There are many aspects to building a finite element analysis model. In several cases, the forms used to create the finite element data are dependent on the selected analysis code and analysis type. Other parts of the model are created using standard forms. Under preferences from the main form in MSC Patran, there is a selection entitled Analysis. The Analysis Preference form accessed by that selection identifies/defines the analysis code which is to be used for this model.

The specified code may be changed at any time during model creation. As much data as possible will be converted if the analysis code is changed after the modeling process has already begun. However, the user must check that the analysis codes support identical or equivalent functionality. If they don’t, the translation may be approximate. The setting of the Analysis Preference determines what will be presented to the user in several areas during the subsequent modeling steps. These customized areas include the material and element libraries (including multi-point constraints), the applicable loads and boundary conditions, and the analysis forms. The selected Analysis Type may also affect the allowable selections in these same areas. For more details, see Analysis Codes (p. 426) in the Patran Reference Manual.

Patran Interface to SAMCEF Preference Guide Finite Elements

Elements Finite elements in MSC Patran simply assigns element topology, such as Quad/4, for standard finite elements. The type of element to be created is not determined until the element properties are assigned. See Element Properties Form for details concerning the SAMCEF element types. Elements can be created either directly using the Element object, or indirectly using the Mesh object. The form below appears when the Object is set on Mesh and the Type is set on Surface

Main Index

Chapter 2: Building a Model 17 Finite Elements

Multi-Point Constraints Multi-point constraints (MPCs) can also be created from the Finite Elements menu. These are special element types which define a rigorous behavior between several specified nodes. The forms for creating MPCs are found by selecting MPC as the Object on the Finite Elements form. The full functionality of the MPC forms are defined in Create Action (FEM Entities) (p. 91) in the Reference Manual - Part III.

MPC Types To create an MPC, first select the type of MPC you want to create from an option menu. The types that will appear in this option menu are dependent on the current settings of the Analysis Code and Analysis Type preferences. The following table summarizes the MPC types that are supported for SAMCEF.

Description

Explicit

Structural

Explicit linear constraint equations between degrees-offreedom (dof) using the .MCE CNLI command.

Rigid Fixed

Creates a rigid body between an independent node and several dependent nodes using the .MCE RIGI command.

Rigid Bar

Structural

Creates an equality relationship between groups of dofs using .LIA GROUPE.

LIA

Structural, Thermal

Creates an equality relationship between 2 dofs using the .LIA command.

Comments: 1. Sliding surfaces are not treated as MPC types. They can be treated as Loads/BCs, using conditions defined in Loads and Boundary Conditions. To create a sliding surface, define an analysis coordinate system with one axis as the surface outward normal. Then enforce a zero translation (displacement), in that direction, for all nodes on the surface. 2. The BACON command .STICK, which can be used for non-homogeneous linking of two meshed parts of a model, is supported as an LBC type.

Chapter 2: Building a Model 19 Finite Elements

Degrees-of-Freedom Whenever a list of degrees-of-freedom is expected for an MPC term, a listbox containing the valid degrees-of-freedom is displayed on the form. A degree-of-freedom is valid if: 1. It is valid for the current Analysis Code Preference. 2. It is valid for the current Analysis Type Preference. 3. It is valid for the selected MPC type. In most cases, all degrees-of-freedom which are valid for the current Analysis Code and Analysis Type preferences are valid for the MPC type. The following degrees-of-freedom are supported by the MSC Patran SAMCEF MPCs for the various analysis types: Degrees-of-Freedom

Patran Interface to SAMCEF Preference Guide Loads and Boundary Conditions

Loads and Boundary Conditions By choosing the Loads/BCs toggle located on the main menu of MSC Patran, the Loads and Boundary Conditions form will appear. When creating loads and boundaries, several option menus are available. The selections made in this option menu will determine which loads and boundary form is presented, and ultimately, which SAMCEF loads and boundaries will be created. The following pages give an introduction to the Loads & Boundary Conditions form, followed by the details of all the loads and boundary conditions supported by the MSC Patran SAMCEF Preference Guide.

Loads & Boundary Conditions Form The Loads & Boundary Conditions form shown below provides the following options for the purpose of creating SAMCEF loads and boundaries. The full functionality of the form is defined in Loads and Boundary Conditions Form (p. 27) in the Patran Reference Manual.

About contacts (part 1)

1. When relative displacements are small, one can assume that a slave node will always be projected onto the same target facet. The facet’s area may be extended when the slave node’s projection is outside. The SAMCEF Preference will add the parameter in the output bank file to force this configuration (and reduce the facets search time) Contact re-profiling is not needed in such a model. 2. When displacements are moderate, one slave node will be in contact with a small number of facets: the and the default values can be overwritten by the user to reduce the computation time. Contact re-profiling is not needed in such a model.

Main Index

84

Patran Interface to SAMCEF Preference Guide Loads and Boundary Conditions

3. When displacements are large, the previous way of working is not suitable because one should define a large and/or a lot of . In such a model, special parameters are added in the output bank file to activate re-profiling: in this case, contact connectivity is recomputed by MECANO at each Newton iteration. Important: Contact conditions cannot be used within a model in which cracks have been defined About contacts (part 2)

1. «.._SDIS» ; small relative displacements of parts; the node is in contact with one and only one facet; the target facet is computed in the pre-processing phase (the choosen facet is the closest one to the node) and will never change; during each analysis step of the non-linear analysis, MECANO tries to (normally) project the node on this facet; if it can, contact is maintained; if it fails, contact is released; a contact release at time step ’i’ can, of course, be re-activated at time step ’j’ > ’i’ 2. «..MDIS»; moderate relative displacements of parts; nodes are in contact with a number of nearest facets selected by the preprocessor; the list of facets is not updated during the non-linear analysis; same rules of «release/reactivation» of contacts as the SDIS is applied but here the module will handle a list of target faces..not one facet alone ! 3. «...LDIS»; large relative displacements of parts; the more general contact condition; nodes are in contact with a number of nearest facets selected, not by the pre-processor, but by the MECANO module; during each time step, the MECANO module will update this list of facets . LDIS option will often leads to huge computation time 4. So, if one is sure that non linear geometries are small AND that relative displacements of parts are small, use «SDIS»; in other cases/in doubt, use «LDIS» About contacts (part 3)

1. «CONT_SROT»;Same as «SDIS « PLUS small rotations hypothesis ; so clearly the more restrictive hypothesis! 2. «TIGH_SROT»;is thightening with small rotations in areas where thightening occurs PLUS «small non linear geometries AND small relative displacements» 3. «TIGH_LROT»;is to be used when any of the TIGH_SROT above assumptions are not verified.

Review of the Analysis Form The Analysis toggle on the main menu for MSC Patran brings up the Analysis form which can be used to request an analysis of the model with the SAMCEF finite element program. For details see The Analysis Form (p. 8) in the MSC.Patran Reference Manual. It can also be used to incorporate the contents of a SAMCEF results file into the database. See Read Results. The following page gives an introduction to the Analysis form used to prepare a SAMCEF analysis. This is followed by detailed descriptions of the subordinate forms that can be displayed from the Analysis form.

The following table shows the allowable selections for the Analyze action. Object Entire Model

Method BACON File Full Run Interactive Run Unix Computed Files (on W2000 only)

The Method indicates how far the translation is to be taken. If BACON File is selected

a complete BACON input file is created.

If Full Run is selected

an Analysis Deck translation is done, and the resulting input deck is submitted to BACON and thereafter to SAMCEF which is run in the background.

If Interactive Run is selected SAMCEF will be run in the foreground, with MSC Patran suspended until the execution is complete. if Unix Computed Files is selected (on W2000 release only)

the Samcef Preference will generate all the files compatible with an analysis to be performed on UNIX machines. However, no remote computation is launched, so you have to manually move these files to a selected UNIX machine to be able to run SAMCEF on this UNIX machine.

Which files have to be moved to the UNIX machine? File Name

Description

jobname.dat

This is a BACON “banque” file created by the interface.

jobname_mesh.dat

This is a BACON “banque” file containing only topology. This file is optional: for many jobs, topology is directly included in the ’jobname.dat file’

Question

Answer

Is the spreadsheet of times saved in Yes. And you’ll retrieve it when you will reload the database the database? again. But don’t forget that all the characteristics you have defined under the Analysis panel and sub-panels will only be saved when the Apply button of the Analysis main panel will be invoked! Can I select more than one time at a glance?

Yes you can select continuous row by using shift-click.

And for non contiguous row?

No, you cannot select non contiguous rows in this release.

How can I use a subset of all the times available in the selected loadcases?

Just click on the Default button to retrieve all the times form the selected loadcases, check the «Manually Handling Times» toggle. Then click/shift-click anywhere in the row(s) of the time(s) you want to delete and click on the «Delete Times» button

I fired some times but I want to recover them?

There is no direct «undo». However, you can force-quit the spreadsheet by clicking on the «Cancel»button. But of course, you’ll loose all the operations you performed on the times since the last moment you access the spreadsheet panel.

What’s the «Strat Time T1...» field This field simply shows the start/end time which can be infer from for? the whole times list. This field cannot be modified. What’s the «Times Increment» field for?

This field indicates the standard time increment that will be used by the integration process to go from ’T1’ to ’T2’. If the «Manually Handling Times» toggle is on, you’ll have the opportunity to change it. But, please note that each time the list of times will change, the increment will be re-computed.

When I modify the list of the selected loadcases (Analysis/Select Loadcases), the times spreadsheet is prompted to me: why?

By doing this, we will warn you that the times list has changed because you certainly add/remove some loadcases containing times steps. There is no way to disable this action.

Question

Answer

The «Add Time...» fields offers me Not available in this release. the opportunity to add times, following a linear progression rule. Is there other way to manually enter a complex list of times?

Answer

Can I import times for an external source (i.e an EXCEL file,..)

Not available in this release.

What is the major difference between the «Default» button in the spreadsheet and the action of adding/removing loadcases from the selected loadcases list?

The «Default» button of the spreadsheet will re-initialize the times list with (and only with) the times available in the selected loadcases: if you had manually added times, they are disregarded. When changing the list of selected loadcases, you simply update the spreadsheet as far as the times retrieved from the selected loadcases are concerned: manual times previously added in the spreadsheet will not be cleaned.

Review of the Read Results Form By choosing the Analysis toggle located on the main form for MSC Patran, an Analysis form will appear.

Selecting Read Results as the Action on the Analysis form allows the user to read results data into the MSC Patran database from text (jobname.des and jobname.fmt) or binary (jobname.des and jobname.fac) SAMCEF files. Other forms that are accessible from here are used to define translation parameters and select the SAMCEF results file. These forms are described on the following pages.

Depending on the selected object (Result Entities, Model, or Both), the model options are the following: Note:

Set the default language in the “settings.pcl” file (Français or English).

OBJECT

DESCRIPTION

Check Model (Results Entities)

The translator will verify that the nodes list and the elements list are the same in MSC Patran and in SAMCEF files. If not, the execution is stopped.

NoCheck Model (Results Entities)

No check is performed.

Database

The translator will verify that the nodes and the elements exist in the MSC Patran database. If not, the model is reloaded from the SAMCEF files into the MSC Patran database.

(Model Data or Both)

If the model is present in the MSC Patran database, the compatibility is checked, as in the option Check Model. Neutral (Model Data)

Main Index

In all cases, the model is translated from the SAMCEF files to a MSC Patran 2.5 Neutral file format: ‘problem’.out.

Chapter 4: Read Results 179 Select Results File

Select Results File How are the SAMCEF results designated in the MSC Patran database?

SAMCEF result types are classified in several categories. The postprocessor of SAMCEF uses a dictionary that gives the characteristics of each type. The SAMPAT3 translator uses the same dictionary file to handle the results found in the file, so the results designation is exactly the same as the one used in SAMCEF. The SAMPAT3 translator creates a primary load case in the MSC Patran database for each SAMCEF module (in uppercase). When Global Variables (e.g., time, frequency) are used associated with secondary load cases, their names are taken from the SAMCEF dictionary (in uppercase too). When transient selected results (SAMCEF codes 9xx or 9xxx) are imported, the translator creates another primary load case, also named with the SAMCEF module name (but in lower case this time). This allows an easy selection during results processing (selection by primary load cases). To avoid confusion, the related Global Variables are named in lowercase too. The Select file form allows the user to select a file to be read. There are several features available. This form is brought up when the user selects the Select Results File button on the Read Results form. The default file filters will change depending on the Current analysis code in the Preferences menu.

Data/Results Translated from the Analysis Code Results File Data

When reading model data from a SAMCEF results file, the following table defines all the data which will be created in the MSC Patran database, and where it is derived from in the results file. No other model data is extracted from the results file. This data are, in most of the cases, sufficient for evaluating any results values. Item Nodes

Important:Reading model data from a SAMCEF results file into a empty Patran database is not at all a valid way to import a Samcef model into Patran!!! Results

Thanks to its direct coupling with the Samcef Results Codes Dictionary, the Samcef Preference is able to import quite almost all of the results Samcef modules (the ones available in the preference) are able to generate. The table below shows the most common results codes generated by Samcef. Note:

The selection of most of the codes described hereafter (but not all) can be driven in the Analysis/Output Requests panel. Depending on the chosen analysis module, some of the codes of the table below may be not present in the results file. The table below does not show ALL the possible codes available in the results file after an analysis.

The following tables described most of the available results after a Structural analysis.

Environment Variables The settings.pcl File The following variables may be set in the “settings.pcl” file: samcef_language

“English” or “Fran´ais.” Set the default language for the analysis forms, the messages produced by the reverse translator and the results designation in the P3 DataBase.

samcef_editor

Set the preferred editor to be used in the “File Control” action of the analyze form.Full path to the editor executable file is highly recommended.

samcef_script_method

“SEPARATE” or “ALL_IN_1” SAMCEF. Runs are performed separately or in one pass. For programmers only.

samcef_unix_shell

(Unix only) “C” or “Bourne.” The scripts generated by the PCL code to run SAMCEF include environment variable definition. This is done by “setenv” or “set ...=”

For example, to generate French labels in the analysis form, enter the command: pref_env_set_string ("samcef_language", "Francais")

Patran Interface to SAMCEF Preference Guide The Forward Translator JobFile

The Forward Translator JobFile The forward translator, PAT3SAM, is driven by a JobFile containing the information and the directives to be used for building the entries in the BACON “banque” data file. The general structure of that file is given below, explained with reference to an example of a JobFile driving a pre-stressed static analysis. Only basics keywords, items,.. are detailed: contents of the JobFile may vary according to the target Patran and/or Samcef releases. Each line has a maximum size of 80 columns and the following syntax: KEYWORD[17] - “ = “ - VALUE[60]

Part 1 The first part of the file contains Job information, including file names etc. The meaning of the Keywords used in the file is defined below: BACON

Name of the main BACON File

BACON MESH

Name of the secondary BACON File if requested (topology: only .NOE/.MAI/.SEL[user's groups])

SAMCEF RELEASE

This part ends when a keyword starting the second part appears (i.e., “$Start”).

Part 2 In this second part there are some directives used to build the BACON “banque” data files. This part ends when the end-of-file is reached. Two types of keyword are recognized: 1. The KEYWORD contains a “$” sign: it contains a directive and an appropriate action to be executed (see below). 1. The KEYWORD doesn't contain any “$” sign: it is a BACON command (or comment) generated by the PCL program. One has only to copy the VALUE in the BACON File. Note that in this part, the first word found in the keyword is always the current BACON label. The directive is to be extracted, starting at the “$” sign.G=
