Which of the following statements is NOT correct: Delaunay triangulation method is a criterion for maintaining that all elements have sensible shape. Delaunay triangulation method is a way to check if any kind of element incompatibility is available in the mesh. Delaunay triangulation method is applicable to both triangular and tetrahedral elements. In Delaunay triangulation method if one node of another element is contained in the circumcircle of the element, it is highly likely that the aspect ratio of the element is not good enough.
