Hi. I'm a student using RADIOSS solver.

I'm doing rigid pole impact analysis using RADIOSS solver.

But I have a problem.

When the structure consist of shell element collide with pole, the deformation does not occur and the analysis is end.

I think this problem happened because of element or contact.

Please help me.

And i attach my RAD file.

Thank you.

    There were a few odd things in the model, no parameters had been set on the contact apart from friction, I set gap, stiffness etc, and also made it a self contact

    You had rotational SPC constraints on all tray nodes, not sure why, but I deleted them

    I also moved your tray a lot closer so you don't waste time modelling free flight.

    You didn't send your engine, so I added my own
