Multicomponent Mixing using a Nozzle: Exercise 3—Preparing the Mesh
A mesh is a computational grid inside, outside, or both inside and outside any closed geometry defined by a CAD surface.
Generating the Mesh
1. In the Flow Analysis Tree, select Domains.
2. In the Properties panel, Mesh tab, for Surface Tessellation, type the following values:
◦ Angle Controls—2
3. In the Properties panel, Model tab, for Mesh Generation, type the following values:
◦ Maximum Cell Size — 0.003
◦ Minimum Cell Size — 0.0001
◦ Cell Size on Surfaces — 0.0015
The values are retained as default settings. You can change these if required.
4. Click 
Generate Mesh to create the mesh for the fluid domain.
