Hi,

I'm trying to do an eigenfrequency computation with a model of 4 solids connected together with "identity pair" as roller or fixed.
Basically one plate supported with 2 rubbers on one beam. Both rubbers ares clamped to the beam. One rubber is clamped to the plate, the other one has a roller pair condition.

The static analysis works well. I put a lateral load on the plate to create shear in rubber. As expected, the fully clamped rubber is subjected to shear stress, and the other no.

But I tried to run and eigenfrequency analysis with the same model. It runs, but the corresponding mode does not appears, I have only mode inside rubber, as the roller identity pair was not working for eigenfrequency problem ...

I attached my file if you want to give a look.

thanks in advance for your help
Martin
