Butterfly case converge

Hello all,

I have a problem creating the case converging in Butterfly and loading the residual values.
I set and calculated the tunnel grading accurately and tried to refine the meshes compatible with the opening size, however, the case isn’t converged.

Also, the biggest problem is that the check mesh component doesn’t run in any way.

Could somebody give any direction?
Thank you
