Hi there,
Let's see if some of you can help me with the following issue, please:
I am working on the mechanical analysis of a satellite (spacecraft(SC)+ payload(PL)). I need to create an external superelement (ESE) of th PL and validate the process by comparing the results obtained with the...

I have a question for you: I would like to know how to get interface forces in random vibration analysis, in order to check bolted joints survival. What I use to do is to place 6 CELAS elements (1 per DOF) in the interface (between an RBE2 and a node) and then I get the 3xRMS forces in the CELAS...
Hi
I found this paper with a explanation about how to perform random analysis of pre-stressed structures in MSC/Nastran.

Hi everybody
Here I come with an easy one. I think my case must be so typical.
I need to combine random vibration and other functional loads (bolts preloads and pressure loads)in a model. I know how to combine functional loads but I don't know how to porceed with random vibration, in order to...
