Hello
I am running fluent coupled to a UDF to simulate a multi body system of discreet elements. I found that I can run the case in serial but in parallel it is generally very sensitive to dynamic mesh settings and even crashes after around 200 time steps with negative cell volume error :"Update-Dynamic-Mesh failed. Negative cell volume detected."
2D, laminar flow, NITA scheme fractional step
Has anyone experienced similar problems for parallel dynamic mesh simulations?
Thanks!
