8 Geometry generation and meshing

Abstract: The process of mesh generation, called triangulation, is a key element of numerical experiments due to its essential influence on the accuracy of numerical results. For this reason a good many tools have been developed to construct meshes of appropriate quality relevant to the peculiarities of the problems under consideration. The most popular FOSS grid generators are Gmsh37 and NETGEN38. In addition to meshing procedures, these programs are supplemented with tools for creating simple geometries.

8.1 General information

We need a discrete representation of a computational domain to solve a mathematical model numerically. Mesh generation is the process of creating ...
