Dupin Meshing: A Parameterization Approach to Planar Hex-Dominant Meshing
Planar hexagonal-dominant (PHex) meshes are an important class of meshes with minimal vertex-degree. They are highly useful in the rationalization of freeform architectural surfaces, for construction with flat steel, glass, or wooden panels of equal thickness. A PHex mesh must contain both convex and concave faces of varying anisotropic shapes due to the planarity constraint. Therefore, while p...
متن کاملThe "Hex-Tet" Hex-Dominant Meshing Algorithm as Implemented in CUBIT
This is a report of the current status of the Hex-Tet algorithm as implemented in the CUBIT toolset. The Hex-Tet algorithm begins by generating a partial hex mesh using an advancing front “Plastering” algorithm. The boundary of any remaining void is optionally “cleaned-up” to improve its shape and/or other properties. The quad boundary is then converted to a triangular boundary by one of three ...
متن کاملParallel Hex Meshing from Volume Fractions
In this work, we introduce a new method for generating Lagrangian computational meshes from Eulerian-based data. We focus specifically on shock physics problems that are relevant to Eulerian-based codes that generate volume fraction data on a Cartesian grid. A step-by-step procedure for generating an allhexahedral mesh is presented. We focus specifically on the challenges of developing a parall...
متن کاملAutomatic scheme selection for toolkit hex meshing
Current hexahedral mesh generation techniques rely on a set of meshing tools, which when combined with geometry decomposition leads to an adequate mesh generation process. Of these tools, sweeping tends to be the workhorse algorithm, accounting for at least 50 per cent of most meshing applications. Constraints which must be met for a volume to be sweepable are derived, and it is proven that the...
متن کاملAutomated Hex Meshing for Turbomachinery Secondary Air System
In this paper, we present a novel process of creating hexahedral meshes for the turbomachinery secondary air system. The meshing process is automated from the geometry import to the mesh setup and requires minimum human interventions. The core of the process is a hexahedral meshing algorithm with a boundary layer mesh automatically created. The hex meshing algorithm combines the pave-sweep, gen...
