Hi FF++ users,  
I am trying to implement a material removal problem with mesh movement. However, after running for some time, I encounter a Bamg error when using the adaptmesh command. I have shared a picture of the error in the comments.  
Could you please suggest the correct way to use movemesh and adaptmesh? Additionally, I would appreciate guidance on how to perform interpolation afterward.

Thanks for your time!

Please see the mesh, I think you will see the problem graphically.
