Finite Element Mesh Generation from Surface Meshes

Advanced Automatic Hexahedral Mesh Generation from Surface Quad Meshes

A purely topological approach for the generation of hexahedral meshes from quadrilateral surface meshes of genus zero has been proposed by M. MüllerHannemann: in a first stage, the input surface mesh is reduced to a single hexahedron by successively eliminating loops from the dual graph of the quad mesh; in the second stage, the hexahedral mesh is constructed by extruding a layer of hexahedra f...

Automatic generation of hexahedral finite element meshes

An algorithm for the generation of hexahedral element meshes is demonstrated. The algorithm starts by creating a structured grid in the interior of an object. Then the boundary region is meshed by means of an isomorphism technique that uses basically 2D-operations. Examples are given that demonstrate the quality of the algorithm.

Multiple Intersections of Finite-Element Surface Meshes

This paper extends a previously proposed algorithm for the intersection of finite-element surface meshes. The new version of the algorithm treats special cases of multiple intersections that were not dealt with in the original version. This paper also describes a class library, in the context of Object Oriented Programming, for the generic handling of several types of surface geometry. This lib...

Hybrid Surface Partitioning of Finite Element Meshes

A hybrid automatic and interactive scheme is developed for partitioning the surfaces of mechanical parts represented by finite element meshes on the basis of geometric discontinuity. Given a finite element surface mesh M in three dimensions, the algorithm firstly finds a partition of M into k subregions k M M ,..., 1 on the basis of 1 G discontinuities in an automatic manner. Secondly, an inter...
