  • RPI SCOREC - Technical Reports
    In this paper a parallel volume meshing procedure whose input is a surface mesh distributed or not is presented In order to help driving the parallel execution a distributed octree is built considering the surface mesh and meshing size attributes The tree is partitioned in parallel using the Recursive Bisection methodology and portions of space are handed out to processors for meshing Volume meshing operates on two techniques i octant

    that meshing is load balanced at all times The approach taken here is to separate surface and volume meshing and present two different methodologies to perform these tasks in parallel For surface meshing which is performed on a model face by model face basis in the sequential case partitioning considers the distribution of individual model faces to processors with possible subdivision if adequate load balance cannot be achieved The technique used in sequential surface meshing is based upon vertex insertion using the Delaunay criterion in parameter space In volume meshing an octree built considering the surface mesh and meshing size attributes is partitioned in parallel using the Recursive Inertial Bisection methodology and portions of space are handed out to processors for meshing Volume meshing operators on two techniques i octant template meshing for interior octants and ii face removals advancing front to fill the space in between the surface mesh and the templated octants Due to the mesh being distributed domains corresponding to the interfaces of the initial partitioning are left unmeshed In order to complete volume meshing the repartitioning of these domains or interfaces is necessary This is referred to as hierarchical repartitioning since face edge and vertex interfaces

    error estimate and a novel vortex core detection technique is used to resolve the flow field of rotor blades in hover For the UH 60A rotor blade a zero thrust case is analyzed initially because the flow field conditions for this case are less severe compared to higher thrust cases of the same rotor blade The effect of tip vortex for the zero thrust UH 60A computations is not strong

    of overlapping patches i comprising a cover i of the domain For an efficient implementation it is very important that the interaction between the patches themselves and between the patches and the boundary is well understood and easily accessible during the runtime of the program We will show that an octree representation of the domain with a tetrahedral mesh at the boundary is an efficient means to provide the needed
