Parallel Hex Meshing from Volume Fractions

چکیده
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 parallel implementation using the message passing interface (MPI) to ensure a continuous, conformal and good quality hex mesh.

Tensor-Guided Hex-Dominant Mesh Generation with Targeted All-Hex Regions
In this paper, we present a method for generating hex-dominant meshes with targeted all-hex regions over closed volumes. The method begins by generating a piecewise-continuous metric tensor field over the volume. This field specifies desired anisotropy and directionality during the subsequent meshing stages. Meshing begins with field-guided tiling of individual structured hexahedral fronts wher...
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...
متن کاملHex-Layer: Layered All-Hex Mesh Generation on Thin Section Solids via Chordal Surface Transformation
This paper proposes chordal surface transform for representation and discretization of thin section solids, such as automobile bodies, plastic injection mold components and sheet metal parts. A multiple-layered all-hex mesh with a high aspect ratio is a typical requirement for mold flow simulation of thin section objects. The chordal surface transform reduces the problem of 3D hex meshing to 2D...
متن کاملA template-based approach for parallel hexahedral two-refinement
In this work we provide a template-based approach for generating locally refined all-hex meshes. We focus specifically on refinement of initially structured grids utilizing a 2-refinement approach where uniformly refined hexes are subdivided into eight child elements. The refinement algorithm consists of identifying marked nodes that are used as the basis for a set of four simple refinement tem...
متن کاملHexahedral Meshing With Varying Element Sizes
Hexahedral (or Hex-) meshes are preferred in a number of scientific and engineering simulations and analyses due to their desired numerical properties. Recent state-of-the-art techniques can generate high quality hex-meshes. However, they typically produce hex-meshes with uniform element sizes and thus may fail to preserve small scale features on the boundary surface. In this work, we present a...
