DAPHNE-3D: A NEW TRANSPORT SOLVER FOR UNSTRUCTURED TETRAHEDRAL MESHES

MeshView: A Tool for Exploring 3D Unstructured Tetrahedral Meshes

We have developed a visualization module, MeshView, for viewing large-scale 3D un-structured tetrahedral nite element meshes. The module includes two diierent approaches for visualization and analysis, plus the capability to edit meshes after the researcher has analyzed the mesh and located problem areas. The rst approach ooers various real-time interactive manipulation options for visualizing ...

A Parallel Compressible 3D Navier-Stokes Solver Using Unstructured Meshes

We describe in this paper a strategy for parallelising a 3D compressible Navier-Stokes solver using unstructured meshes on a class of message-passing MIMD machines. The performance results obtained on two parallel machines, the Meiko Concerto and Intel iPSC860 are presented and compared to those obtained on CRAY.

Force-Directed Methods for Smoothing Unstructured Triangular and Tetrahedral Meshes

A spectral volume Navier-Stokes solver on unstructured tetrahedral grids

The spectral volume (SV) method was first introduced as a method to solve systems of convection equations, like the Euler equations, in a series of papers by Wang et al., e.g. [1] and the references therein. It is related to the discontinuous Galerkin (DG) method, in the sense that it also uses high-order polynomials to approximate the solution in each grid cell, and Riemann solvers to deal wit...

Techniques for Visualizing 3d Unstructured Meshes

We present a computational module for interactively visualizing, large-scale, 3D un-structured meshes. Scientists and engineers routinely solve large-scale computational boundary value problems on unstructured grids. These grids typically range from several hundred thousand elements to millions of elements. With this ability to solve such large-scale problems comes the challenge of viewing the ...
