I have one problem. Hopefully you are willing to help and I really appreciate for it. My model dealing with dynamic mesh. Initially, it is a fixed fluid domain. Additional fluid domain will be added for certain period then finally there is increment to the initially fixed fluid domain. Few pictures have been attached as below: Pic 1 is the fixed fluid domain. Pic 2 is final fluid domain after certain period. Dynamic mesh has been applied to top surface as rigid body motion as shown in Pic 3. Pic 4-7 showing the grid at few segment. Problem occurred as the mesh has been collapsed after additional fluid domain with dynamic mesh. Pls help and provide solution in solving. Thanks for your help.
