Nastran: how to obtain 1-sigma stresses for SOL 111
(OP)
How can I obtain from a sol 111, random vibration analysis with input PSD curve, the 1-sigma, 2 sigma and 3-sigma stresses in MSC/Nastran?
Thank you
Thank you

Random = n (same number as the RLOAD2 table ID)
to your subcase control and reference the PSD in your RLOAD2 card.
For RMS Values, you would add something like:
XYPLOT ACCEL PSDF / NodeID(direction)
Hope this helps. I might try it out myself.
