Launch python script with abaqus command

Question

I have a command file (.cmd) which I use to launch Abaqus command line windows. Then, I use the command 'abaqus python test.py' to launch python command inside Abaqus.

Now, I would like to use a python script to do that. I try something like this but doesn't work. Someone know the trick ?

Thanks !!

import subprocess

AbaqusPath=r"C:\Abaqus\script\abaqus.cmd"
args= AbaqusPath + "-abaqus python test.py"
subprocess.call(args)

what are you trying to do ? run a script that does stuff in CAE or run a script that does some analysis etc (but no CAE tasks) ? — will

Using .cmd-file:

This way might work with cmd file:

abaqusPath = "C:\\Abaqus\\script\\abaqus.cmd /C"
args = AbaqusPath + "abaqus python test.py"
subprocess.call(args)

Flag /C is needed to run command and then terminate.

Easiest way:

Just add the folder with abaqus commands (typical path C:\Abaqus\Commands) into the PATH variable of the system. This will give the access to commands like abaqus, abq6141 etc. in cmd directly.

When just use the following in your script:

subprocess.call("abaqus python test.py")

Using .bat-file:

If the configuration of PATH variable is impossible and the first way does not work, .bat-files from abaqus can be used as follows:

abaqusPath = "C:\\Abaqus\\Commands\\abaqus.bat "
args = AbaqusPath + "python test.py"
subprocess.call(args)

Could I get the return of subprocess call ? To know if something went wrong ?

Yes, as I understand all of them return the value of exit. Just assign it to some variable, for instance a = subprocess.call(). Then you can check if it is non-zero.

I've never had any success using just string arguments for subprocess functions.

I would try it this way:

import subprocess

abaqus_path = r"C:\Abaqus\script\abaqus.cmd"
subprocess.call([abaqus_path, '-abaqus', 'python', 'test.py'])
