I'm working on a simulation project using LS-DYNA and integrating it with a Python-based workflow using PyDyna. The same .k file runs successfully in GUI (Graphical User Interface) mode, but fails when executed via PyDyna.
from ansys.dyna.core.run import run_dyna
run_dyna("test.k", working_directory=r"../test3")
>>> test.k manages the multiple .k files or stages of a simulation.
Error Message (from lsrun.out.txt):
*** Error 10149 (KEY+149)

turn on the built in case handling capability
