I made some shape changes

I will get an error when I perform the coupling operation.

“System coupling run completed with errors.  Fluid Flow (Fluent) (Solution 3) reported: Fluent encountered fatal error after sync point Solve: received a fatal signal (Segmentation fault). Please do not save the project if you would like to recover to the last saved state.”

I think it should be a problem with moving grid settings.

I am not familiar with moving meshes, so I mimicked the online example to set the dynamic mesh parameters.

Dynamic mesh parameters are as follows

My confusion is as follows

1. Is the dynamic mesh setting for the fluid-solid coupling surface reasonable?

2. Among them, I only set the lf-dc surface of the flow field and the solid contact part as the fluid-solid coupling surface. Does the other surface of the flow field need to be set as a dynamic mesh? These faces are not in contact with the solid part

as you have hex mesh, you may need to use layering.
