Problem using APDL from command line

Problem using APDL from command line

Problem using APDL from command line


I’m trying to run APDL scripts from MatLab using the system command. I have an Ansys script which opens up a results file, filters for elements using specific materials, finds the max stress element and saves it to a file which can then be read back into MatLab. This file contains the following, and runs no problem when using the APDL GUI using File-> Read Input From…

/FILNAME,submod ! New jobname = submod
/POST1 ! Enter POST1
FILE,submod,rst ! Use coarse model results file
!SelectElements with nickel material 2
!SelectElements with nickel material 2
PLNSOL, S,EQV, 0,1.0
!Write to output file

I’m trying to call this from the command line using a batch file containing the following:

SET KMP_STACKSIZE=4096k & "C:\Program Files\ANSYS Inc\v190\ansys\bin\winx64\ANSYS190.exe" -dir "D:\Temp\ANSYSTemp" -i Test.txt

And the max stress is shown to be -0.126765060E+31 (which I assume is some kind of overflow value). The VWRITE command just writes ***************, *************** as the number is too big for the specified format.

It’s kind of driving me insane… any ideas on why this might be happening? I can provide submod.rst if anyone wants to do a test. Any help will be much appreciated!

RE: Problem using APDL from command line

Can you share the rst file?

RE: Problem using APDL from command line

I have result for your code. But how can I upload files here?
