Environment Variables

ABAQUS_BAT_PATH

In order to use Abaqus command to execute the Python script and submit the job, you need to tell abqpy where the Abaqus command located. Usually, Abaqus command locates in a directory like this:

C:/SIMULIA/Commands/abaqus.bat

You can add the directory C:/SIMULIA/Commands to the system environment variable Path, or you can create a new system variable named ABAQUS_BAT_PATH, and set the value to the file path of the Abaqus command, i.e., C:/SIMULIA/Commands/abaqus.bat.

ABAQUS_COMMAND_OPTIONS

The default execution procedure invoked by abqpy inside the Python interpreter environment where it is installed is to run one of the two following command lines:

1. When there is a import abaqus or from abaqus import ... statement:

   abaqus cae noGUI=script.py -- [args ...]
   

2. When there is a import odbAccess or from odbAccess import ... statement:

   abaqus python script.py [args ...]
   

However, there are other execution procedures that can be run with the abaqus command and also another options that could be passed to these commands. To define these procedures and options you can create a new system environment variable named ABAQUS_COMMAND_OPTIONS, and set a dictionary to this variable with the options you want to use. The values of the dictionary keys would be booleans or strings, e.g.: {'noGUI':True, 'database':'file.odb'}

The possible options are:

1. Using abaqus cae command line options (import abaqus module):

   {
       'noGUI': bool,
       'database': 'database-file',
       'replay': 'replay-file',
       'recover': 'journal-file',
       'startup': 'startup-file',
       'noenvstartup': bool,
       'noSavedOptions': bool,
       'noSavedGuiPrefs': bool,
       'noStartupDialog': bool,
       'custom': 'script-file',
       'guiTester': 'GUI-script',
       'guiRecord': bool,
       'guiNoRecord': bool,
   }
   

2. Using abaqus python command line options (import odbAccess module):

   {
       'sim': 'sim_file_name',
       'log': 'log_file_name',
   }
   

One advantage in using this alternative is to change the options at run time inside the code.

Example

The snippet bellow changes the default procedure options before calling abaqus cae command procedure, at run time.

import os
os.environ['ABAQUS_COMMAND_OPTIONS'] = str({'noGUI': False, 'database':'file.odb'})

from abaqus import *
...

In this specific case, the procedure will use the graphical user interface (GUI mode) and load a database file, i.e., it will run the following command line.

abaqus cae script=script.py database=file.odb -- [args ...]
