** WARNING 702530 ** Extremely poor element matching at the 3D Part and 3D Insert interface. Convergence and accurate results unlikely.
Ideally the faces of adjacent part tetrahedron and insert tetrahedron elements at the part-insert interface should match each other perfectly. If this is not the case, the solver tries to correct it internally. If this automatic correction is unsuccessful, solver convergence problems can arise which may lead to poor quality results. In this case the matching is extremely poor and convergence and accurate results are unlikely.
Ensure that the geometries at the interfaces are consistent and that the insert facets are on the same plane and of a similar dimension to those on part.
