Hello sir,

I am currently using MSC Nastran, Patran for random response anlysis because it is quite easy. I want to do that in hypermesh/optistruct. but the tutoril does not match with my requirement.

1. I have input in terms of acceleration as base excitation.

2. I have Frequency Input 20 to 2000 Hz with 100Hz increment.

3. I have a critical damping condition of 0.3.

4. I have PSD Input as follow

    20 Hz- +3 dB/octave

    20- 100 Hz - 0.28
