I am doing Random Vibration Simulation project using OptiStruct and our Customer require us to evaluate RMS stress at every single mode to verify the effect of the mode on the system/module.
Now, what we already know here is the RMS stress throughout the simulation and not per frequency.
Is this possible in OptiStruct?
Please help us how and what inputs we should integrate in our model so that we can be able to evaluate the RMS stress at every single mode.
I really appreciate your response since this is very urgent.
