The objective of this work is to compare the influence of hexahedral mesh vs tetrahedral mesh in cervical spine and its effect to measure the biomechanical stresses and its motion at different motion segments. The model was meshed using linear hexahedral mesh and linear tetrahedral mesh. A ...
(2009) [56], who could find good agreement for distal bone sections of the radius using longer bone sections (hence having damage far from the boundaries) and using tetrahedral elements. In the present study, we could improve the prediction agreement by using thinner elements in the cortex, ...
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...

Mesh untanglingWhisker weavingWe investigate a well-motivated mesh untangling objective function whose optimization automatically produces non-inverted elements when possible. Examples show the procedure is highly effective on tetrahedral meshes and on many hexahedral meshes constructed via mapping or sweeping ...
Comparison of hexahedral, tetrahedral and polyhedral mesh for reproducing the flow field around an isolated building by LESPolyhedral mesh is very economic, which can achieve\nacceptable accuracy, while less calculation resource is required.\nBoundary layer mesh is important to reproduce accurate\n...
tetrahedral meshhexahedral meshDesign and analysis softwares are the backbone of todays rapidly developing engineering world. Due to the unmatched flexibility and fair accuracy of these tools, a modern design engineer relies heavily on these techniques. However, it is very important to note that one...

The linear hexahedral and tetrahedral elements are joined without linking elements of pyramidal shape. Two triangular faces are constrained by a quadrilateral face in an irregular mesh with hanging edges. The shape functions are not conforming on the interface. However, test computations proved a good...
