Natural frequency.
Natural frequency.
(OP)
Hi,
Is it possible to extract the natural frequency of a system with soft gel-like material contained in a rigid body container? The gel is in contact with the container. I can extract the natural frequency of the gel (not including the container in the model), but am having trouble to include the container. In addition, how can I specify that they are in contact? ABAQUS gave me error message saying that *contact is only available in Explicit. Thanks a bunch!

2) If u use acoustic elements make sure u use correct boundary conditions for the free surface of the gel (d.o.f. 8/pressure = 0.)
3) connect fluid and structure via tie constraint. fluid = slave !
4) run frequency analysis
Good luck, Pam
