Persistent Negative Cell Volume Error
Hi all - I am completing a dynamic mesh simulation with a mesh that moves node by node. The simulation works for an incredibly coarse mesh, but anything finer will give the "negative cell volume" error. For accuracy, I need a finer mesh. I have tried using a smaller time step, but I still get the error.
Any ideas? I have been making mesh after mesh after mesh trying to get something to work without any luck. Is there any way to have a very coarse mesh but it still be accurate?
