dynamicMesh
 

Hello,

I want to simulate a tube that decreases and after that increases its diameter at different parts (cellZones) according to some user determined compression value. Could you recommend me which motion solver should I use?

I tried to use displacementLinearMotion, but it compresses the whole mesh. It could not be applied on different cellZones. How could I make it work on different cellZones? Or how could I compile my own motionSolver?

Thanks a lot!
Best Regards!
