Furthermore, hexahedral meshes yield more accurate solutions than their tetrahedral counterparts for the same number of edges. Our adaption procedure uses an edge data structure that facilitates efficient subdivision by allowing individual edges to be marked for refinement or coarsening. Pyramids and ...
and Kenji Shimada2 The Department of Mechanical Engineering, Carnegie Mellon University, 1soji@andrew.cmu.edu 2shimada@cmu.edu ABSTRACT This paper describes a new method for increasing the number and the volume of hexahedral and prism elements in a hex-dominant mesh by topological transformations. ...
For the sake of clarity, and because this is the nomenclature used in Pmarc-12, hexahedral scan volumes will be referred to as "rectangular," even though their sides are not necessarily orthogonal. To display scan volumes, click on the appropriate icon in the toolbar. The parameter being ...

According to the existing hexahedralbased, approximation scheme over simple or rough hexahedral meshes it is difficult to get the solid models which designers want to model without using some special rules. We devise a set of solid subdivision rules to facilitate a simple subdivision procedure. In ...

Furthermore, related mesh quality improvement techniques use a combination of quadrilateral/hexahedral subdivision, anisotropic remeshing, and those based on conformal remapping =-=...
MFEM-1 and MFEM-2 use regular hexahedral grids, while MFEM-3, MFEM-4, and MFEM-5 use unstructured tetrahedral grids. Apart from the different grid types, these meshes also vary in density. Among them, MFEM-5 uses an adaptive algorithm based on a posteriori error estimates to generate the...
In this simulation, fully integrated eight-node hexahedral elements are used. The effective size of the elements within the area of crack propagation is 0.988 mm. The material properties of the specimen are presented in Table 4. The final shape of the crack is shown in two different views ...
