SUMMARY This paper describes a method to extrude near-body volume meshes that exploits topologically adaptive generalized elements to improve local mesh quality. Specifically, an advancing layer algorithm for extruding volume meshes from surface meshes of arbitrary topology, appropriate for viscous fluid flows, is discussed. First, a two-layer reference… (More)

An algorithm to generate volume meshes by extrusion from surface meshes of arbitrary topology is presented. The algorithm utilizes a three-step, advancing layer scheme to extrude a smooth volume mesh starting from an initial surface mesh. First, a locally orthogonal reference mesh is algebraically generated for the layer. The reference mesh is then smoothed… (More)

We report a new algorithm for solving the moving boundary problem of oxidation of silicon in 3D structures. The algorithm solves many of the boundary and mesh quality problems that makes 3D oxidation simulations challenging. Using this algorithm, we demonstrate that complicated 3D oxidation steps can be performed and results can be obtained in a reasonable… (More)

A novel algorithm to extrude smooth, near-body volume meshes from surface meshes of arbitrary topology is presented. These meshes are classified as generalized meshes because multiple element topologies may be present within the same mesh. The algorithm utilizes a three-step, parabolic scheme based on the Poisson equation used in structured grid generation… (More)
