dynamic mesh: cells get crowded....Help
1 Attachment(s)
I was using dynamic mesh in my 2D model and it worked well. However, when I change a bit my model and refine my mesh, I get negative volume cells. From some reason during moving, the cells get crowded at a specific place and gernerate negative volume.
Does someone have an idea :confused:????? I am stuck!!!!! |
in per time step is the convergence well?you can check the mesh and the setting of dynamic mech.

Thank you for your respond.
I am sure there are parametrs that are not defined well. I used layering remeshing ..and went through the tutorial It starts from the first time step that the cells are getting very small just but just in one point. It looks like it the remeshing at that point doesn't work well from some reason... |
