Mesh Generation

Introduction

Fluidity has very limited mesh generation capabilities, and in this context mesh-generation should not be confused with mesh adaptivity. However, mesh generation is an integral part of fluid-flow simulations. The AMCG packages (if you installed with a package manager) include Gmsh, a free mesh generator. Here we go through mesh conventions, formats and list software you can use to generate unstructured meshes

Mesh File Formats

• Only surface mesh is required
• Describe how vertical extrusion is done
