Mixing Tank: 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 = Stator
• 2 = Rotor
1. In the Flow Analysis Tree, select 
Domains.
Domains.2. In the Properties panel, Model tab, for Mesh Generation, type the following values:
◦ Maximum Cell Size — 0.01
◦ Minimum Cell Size — 0.001
◦ Cell Size on Surfaces — 0.01
The values are retained as default settings. You can change these if required.
3. Click 
Generate Mesh to create the mesh for the fluid domain.
Generate Mesh to create the mesh for the fluid domain.4. Select Domains.
Domains.5. In the Properties panel, View tab, set Keep drawing, Grid, and Outline to Yes. The mesh for the boundary FLUID_ROTOR appears in the graphics window.
6. Under 
Boundary Conditions > 
General Boundaries > , right-click FLUID_ROTOR/FLUID_STATOR and select Separate and Connect.
