moving mesh with calculated boundary deformation
 

Hello,
my code calculates the deformation of a floating object surrounded by a membrane. (The membrane encloses a liquid and floats in a (rigid) channel.)

How can I use the dynamicMotionSolver for the movement of mesh vertices? My code calculates the movement of the membrane, and the channel boundary is fixed. All other points must be solved.

It seems that the existing methods can only handle solid body movements.
