Introduction

ABAQUS CAE provides a graphical user interface that allows the user to create

finite

element models that can then be analyzed in ABAQUS Standard.  For every feature in

CAE, there is a corresponding Python script command that the program uses when

creating the model.  If the language is understood well enough, an entire model can be

created simply by running a script file.

While one could write an entire script from scratch, ABAQUS provides several easier

methods that autogenerate Python commands.  When a model is created in CAE, two

files are automatically created in the work directory.  The replay file records every action

that is performed in CAE including camera zoom/panning commands and also any

mistakes that were made and then corrected.

This file can be run to “replay” all the work

that has been done on the model.  The recover file records only the minimum necessary

commands to recreate the model.  If an error occurs and CAE closes without saving, the

recover file can be run to recreate the model.  When a model is saved, CAE uses the

recover file to write a journal file.  The journal file is a comprehensive script that shows

all work saved on the model.  Note that the recover file is deleted whenever the model is

saved and all of its commands are transferred to the journal file. The recover and journal

files provide an easy alternative to writing Python scripts from scratch.  One can simply

define a model in CAE and then save the Python commands from the recover or journal

files as a separate script file.

There are several valuable sources of information pertaining to scripting in ABAQUS.

The

ABAQUS Scripting User‟s Manual and ABAQUS Scripting Reference Manua

l are

invaluable resources that are included in the ABAQUS documentation.  The user‟s

manual gives an overview to scripting while the reference manual provides in-depth

coverage of every scripting command used in ABAQUS.  Another source of information
