However, it turns out to be an error indicating high aspect ratio cells. I have added the geo file and error message with this email. Can anyone have any idea regarding this issue? How can I overcome this problem? I have been trying to fix it for the last few weeks. Any suggestion will be great for me. Thanks

Your mesh seems fine. But indeed you create very "elongated" prisms by extruding the surface mesh along the z direction with a single layer...
