Hi! I'm doing a seam-crack with a radial mesh on a 2D-shell.abaqus 

I have this problem when i submit :"Triangles, Tetrahedra and wedges may not be used in a contour integral region. 56 elements are within a contour region. The elements are identified in element set ErrElemIncorrContInteg."

How can i fix it?

Thanks in advance
