Natural Convection 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, Model tab, for Mesh Generation, type the following values:
Maximum Cell Size0.005
Minimum Cell Size0.0005
Cell Size on Surfaces0.005
3. Click Generate Mesh to create the mesh for the fluid domain. If the Info dialog box opens, click Yes to convert all the units.
Viewing the Mesh
1. Click in the Graphics toolbar to display the style elements. Select No Hidden, Hidden Line, or Wireframe to display the mesh.
2. Clear CAD Bodies and Flow Analysis Bodies.
3. Under Domains, select CONCENTRIC_ANNULUS. In the View panel, click Show to display the selected domains.
4. In the Properties panel, View tab, set Grid, and Outline to Yes. The mesh for the boundary CONCENTRIC_ANNULUS appears in the graphics window.
