Hi Federico,

Thanks for your reply. I get no error message. It is just the program does not run, or it does not create .lock file in the project folder.The path I brougtht above was from the manual. I am using the / in my syntax, like

"C:\Program Files\ANSYS Inc\v231\Rocky\bin\Rocky.exe" -simulate "E:ROCKY DEM\Workshops or tutorials\Static Angle_BatchRocky23\StaticAngleBatch.rocky" -resume=1 -ncpus=20
