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)
