Okay now I managed to start ls dyna in windows PowerShell with a little bit help from chat gpt, I defined variable in powershell with $env:ANSYS_SYSDIR = "winx64" line.
Then I used below command
& "C:\Program Files\ANSYS Inc\v232\ansys\bin\winx64\LSDYNA.exe" -dp -i=DynaOpt.inp
after that lsdyna starts running but now I am encountring with the ls dyna error below :
*** Error 70004 (OTH+4)
invalid option on the command line:
-i=dynaopt .inp
by the way I want to run optimization with 8 cores( I have valid lsdyna license for 8 cores)
