STKO’s NDMaterial tester launching OpenSees

Dear STKO Support,

I’m currently using STKO with OpenSees version 3.7.1, and I’m encountering a persistent issue when trying to run material test.

I’ve installed OpenSees compiled by prof. Nicola Tarque in the default position C:\OpenSees-Solvers. (OpenSees, version 3.4 Features: Sequential OpenSees, Parallel OpenSees)

However, when using the material tester, I get the following error in the terminal window:

Traceback (most recent call last):
File "C:\Program Files/STKO\external_solvers\opensees\physical_properties\utils\tester\TesterND.py", line 807, in onTestClicked
self.tester.run()
File "C:\Program Files/STKO\external_solvers\opensees\physical_properties\utils\tester\TesterND.py", line 255, in run
for item in tu.executeAsync([opensees_cmd, temp_script_file_rel], temp_dir):
File "C:\Program Files/STKO\external_solvers\opensees\utils\Gui\TesterUtils.py", line 52, in executeAsync
raise Exception(command, exitCode, output)
Exception: (['C:/OpenSees-Solvers/opensees.bat', 'script.tcl'], 3221225477, b'')

Can you please help me to understand the issue?
Thank you in advance.

With kind regards,
Federica

What material model are you testing?
Can you share your model to see what the issue could be?

Hi,

I was using DamageTC3D, but apparently the error disappeared now, so no material problem any more :D

Thank you!
