Thank you Erik,

Sorry for that, I didn't know that and I will open new discussion it for future questions. 

for this problem, I exactly needs the command that goes to Modal and then goes to Random vibration. I already checked the help, but I am not sure which command should be used for pressure PSD load on the surfaces in Workbench. 

I dont know how to find the VM203 in the apdl verification manual.


Thank you!
