Hi, Dear all,

attached model is able to get converge, however, the fluid do not deform with solid,
May I know why?

I think this is belong to post processing data, since the wall has displacement, just it separate from fluid only.
but i just cannot show the result in correct way.

Solution is in spatial mesh.

Any idea?

p/s: you may run the model to see the solution in the last 2D plot group. 0.04s. The solid side detach from fluid.OMG!

Thank you.
