BMsweep: Locating Interior Nodes During Sweeping.
Matthew L. Staten, Scott A. Canann, Steven James Owen · 1998
BMSweep is a new algorithm to determine the location of interior nodes while volume sweeping. BMSweep uses background mesh interpolation to locate interior nodes while sweeping two and one half dimensional volumes. Three dimensional volumes can be swept using BMSweep after being decomposed into two and one half dimensional volumes. The interpolation method provides for quality element creation while allowing the volume boundary to vary. KEYWORDS: mesh generation, sweep, background mesh, hexahedra, mapped meshing, 2.5D. 2.0 Introduction For a variety of reasons, hexahedral elements are often prefered over tetrahedral elements for use in finite element analysis[1,2]. However, unlike tetrahedral meshes, hexahedral meshes are much more constrained and, therefore, much more difficult to generate[3]. Sweeping is a technology that has received significant research in the past few years and is a method of meshing two and one half dimensional volumes with an all hex mesh [4-9]. A two and one h...
