Abstract

Finite Element Analysis (FEA) is a method of performing mathematical analysis on complex geometry used extensively by both scientists and engineers. An important step in performing the analysis is the mesh generation process. This is the process of dividing a volume into small individual elements (finite elements). Currently there are two common shapes for these elements: tetrahedrons and hexahedrons. Due to the fact that tetrahedrons are a much simpler geometric shape, many robust tetrahedral meshing algorithms have been produced and find a wide range of uses. For solid modeling problems however, hexahedrons are the element of choice. Unfortunately there has been less success in developing robust meshing algorithms for hexahedrons. Because of this, much more effort is needed to produce a hexahedral mesh, often requiring hundreds of man-hours.
