Convergence for a transient problem

Hello everyone.
I am trying to solve a problem where a shock wave passes trough a tube. I put as an output boundary a sinusoidal condition for the pressure (udf). My problem is whenever the wave passes through i have a convergence problem ( abnormal discontinuity in the pressure). And so my residuals are never converging. I thought about refining the mesh with a dynamic mesh but don't very know how to do it so it can follow the wave. Do you have any other solutions/suggestions ? Thank you in advance |
