Comparison of Elements (Triangle, Rectangle, Tetrahedron, Hexahedron)
In the stress analysis, it is confirmed that the 2nd-order triangular elements yield the same level of analysis accuracy as the 2nd-order rectangular elements.
See the following links for the details.
Accuracy Comparison of Triangular and Rectangular Elements
Accuracy Comparison of Tetrahedral and Hexahedral Elements
Obtain the project file used for comparing the tetrahedral and hexahedral elements. (Save the project file before open.)
Currently, the hexahedral Case4 (8 layers, mesh size: 1.0) is set. To change it to tetrahedral element, change the setting from semi-automatic meshing to automatic meshing.
