Hello!,

Post the FEMAP model to better investigate the problem, but in my opinion the mesh quality is wrong, I suggest to delete mesh and create again a valid CQUAD4 shell mesh, with mapped meshing, forgot at all of having triangular elements, later when solving your analysis the obtained results will have an excellent accuracy.

Best regards,
Blas.
