Reply To: How do I define a specific dynamic mesh size?

[Gengyan Liu]

I am using 22 v1, and I am using triangle. The simulation is axiosymmetric. I do not have inflation layers. Also, I have realized that after 1 iteration, it just says divergence in AMG solver. I have tried to lower the mesh density to around 20% of what is visible here, then it runs perfectly fine. I am using 5e-9 second time steps. I know that the wall does not have enough time to move more than 1 cell length, so no negative cell volume problem. Should I just update ansys to the 24 version? I am worried about backwards compatibility if something happens.
