random vibration analysis in patran/nastran

Good evening, everyone.

I would perform a random analysis in nastran using patran as a pre-processor but I just can't figure out how to do it. I tried to search for some tutorials on the internet of course but found nothing that helped me. It seemed to me to understand that you have to compile a "hand" input file by providing the data regarding the frequency signal to use the nastran sol111 and it seems to me a rather complex operation, even because, if I did, I don't know how to have indications about reading the output... It seemed to me that ansys instead has a dedicated pre-processing tool but unfortunately I don't know how to use this software.
It seems impossible for Patran not to have provided... I think my perplexity is only due to my ignorance!:redface:
Can any of you help me?

Thank you very much!
