Cabin Radiation with Convection and Radiation: Cabin Radiation Exercise 4—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 Size — 0.01
◦ Minimum Cell Size — 0.001
◦ Cell Size on Surfaces — 0.005
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.
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. Select Domains.
4. In the Functions panel click
Turn on/off view properties and select the following from the list:
Hide all surfaces,
Hide all grids, and
Hide all outlines.
5. To view the surface, mesh or outline for a boundary, in the Flow Analysis Tree, under
Boundary Conditions >
General Boundaries select the boundary
OFFICE_ROOM_1_FLUID.
6. In the Properties panel, View tab, set Surface, Grid, and Outline to Yes. The mesh for the boundary OFFICE_ROOM_1_FLUID appears in the graphics window.
