FEMAP PSD Anslysis

[midsidenode]

I was wondering if someone could give me some free FEMAP tech support as my access to Siemens has lapsed. The question goes like this: I can successfully complete a solve for a laminate structure’s normal modes (#2 Normal Modes/Eigen Value), followed by a solve for the modal frequencies (#4 Frequency Harmonic Response) – where I can read the laminate max failure index and laminate min strength ratio related to each of the natural frequencies. Nevertheless, I am unable to read the laminate max failure index and laminate min strength ratio when completing a solve for the PSD analysis (#6 Random Response). I am choosing stress and strain on the Output Requests card and SRCOMPs on the Bulk Data card. What would be the problem?

If you request Nastran to print the results to the f06, does it have the laminate failure indices in it? I don't think Nastran provides this because they can't be calculated by the standard means like it would in a static solution.
