      Mechanical doesn’t support pressure PSD, so it would have to be defined with a commands object. Then the RPSD has to be done with POST26 commands. Modal results need to be requested for this. By default Mechanical deletes the modal results from the rst file to save disk and these are needed for the RPSD.
