Dynamic Mesh.. Layering.. cell addition
My problem has a cylinder, the top surface of which moves with time. The top velocity is known. I am using layer addition and removal. The velocity is very small and hence the displacement per time step is small too (using adjustTimeStep). The problem I am facing is that when a new cell is formed its thickness is very small and hence the solution diverges. Let me illustrate with an example.
Say my cell thickness is 0.5. What I would ideally want to happen is that the cell grows up to height 0.6 and then when the new cell forms the old cell splits into two with one of size 0.5 and other of size 0.1
What is happening currently is that the cell grows up to 0.6 and then new cell forms on the top of it. It initially has very small thickness and hence causes divergence.
Can someone please suggest me the correct way to solve this issue.
Thanks in advance,
