That error says that the element module (ShellMITC4, i.e. the finite element formulation you are using) requires a quad mesh (4 nodes) while you meshed the surface with triangles (3 nodes).

By default the mesh is unstructured and triangular, you can make it quadrilateral in the mesh controls dialog:
