The region can be subdivided into triangular or quadrilateral elements by considering four nodes that form a quadrilateral such as the area in Fig.4. There are two types of automatic triangulation for mesh generation, i.e. quadrilateral division and Delaunay technique. Either linear or quadratic order can be selected: linear elements (3-node triangle or 4-node quadrilateral); quadratic elements (6-node triangle or 8-node quadrilateral). When the mesh has been generated, this plan grid then serves as the reference for the assignment of all material properties, supports and loadings that are placed on the grid using the mouse.
