The first procedure is for purely tetrahedral grids; unfortunately, repeated anisotropic adaptation may significantly deteriorate the quality of the mesh. Hexahedral elements, on the other hand, can be subdivided anisotropically without mesh quality problems. Furthermore, hexahedral meshes yield more ...
Tetrahedral Volume Elements The polyhedral mesh is derived directly from the tetrahedral mesh by forming polygons around each node in the tetrahedral mesh. Volume Element Counts Convergence The pressure residual for each mesh type is shown below. Pressure Residuals Monitor The solution on the polyhedral...

aInitially, a hexahedral element was used as its accuracy is higher than that of tetrahedral element but the mesh failed as the model surface became rougher. 最初,一个hexahedral元素使用了,因为它的准确性那高于四面体元素,但滤网无法作为式样表面变得更加粗砺。 [translate] ...

Overall, we concluded, for the simplified femur, that tetrahedral linear element allowed results more closely to theoretical ones, but hexahedral quadratic elements seem to be more stable and less influenced to the degree of refinement (NDOF) of the mesh. It was not possible to correlate these ...
