I am trying to determine the rms stress outputs from a modal frequency analysis.
I am able to view the stresses at different frequency values, but could not find an output to combine them into rms values with a given confidence interval.
OptiStruct doesn't output rms stress results currently.
For random response analysis, the commands XYPLOT, XYPUNCH, and XYPEAK can be used to request the results of displacements, velocities, and accelerations.
