I am trying to model the circular moving wall with prescribed mesh displacement inside the closed chamber. The amplitude and the period of velocity are 30 m/s and 200 micro seconds, respectively. I am using the fluid structure interaction. the closed chamber has 3 no slip walls and one of the chamber walls is a membrane. However, I got an error. When I reduced the amplitude to 0.1 m/s and increased the period to 1s, the problem was solved. Could you please let me know how can I solve the issue when the amplitude is 30 m/s and period is 275 micro seconds?
Do you have a better suggestion to model the shock wave?
I tried to reduce the mesh size and time step but it is not the solution.
Thanks
