Default COMET: fluid-solid interaction

Hallo! I am a phD Student of the University of Karlsruhe. I am trying to perform a Fluid-solid interaction simulation of a valve inside a water duct. The valve is made of rubber. the coupling actually works, and the valve move hiself, but unfortunately only with small deformations. How can I get large deformations of the mesh? As the mesh moves hiself more than two single cells, the geometry break down. and the simulation can not keep on running. I am using the VSMO command, and of course, MOVGR. But it seemed it does not work as it should. Can you help me in anyway? I am looking forward to hear from you. Best regards, Mauro Malve

Hello Mauro,

I 've one question regarding your work. You have mentioned that the deformation of rubber is small. Is COMET able to handle rubber (highly non linear)??

Hallo F.K.,

Same group here, don't be puzzled by a third party chiming in.

No, I don't think so. At least not out of the box. What we are interested in at the moment is the mesh dynamics.

Our application will be even more non linear, actually, but without sufficient mesh deformation and dynamics, we won't even get that far
