Building the Mesh

This section describes the step-by-step procedure for preparing the mesh for the cabin radiation model that contains chair, table, window, floor and wall. The mesh is created using the General Mesher.

Select General Mesher in the Mesh Panel.
Select CAD Surfaces cabin_chair, cabin_floor, cabin_front_wall, cabin_inner_wall, cabin_table, cabin_top_wall and cabin_window in the Geometric Entities Panel.
Enter Maximum Cell Size as 0.02, Minimum Cell Size as 0.001 and Cell Size on Surfaces as 0.01 in the Properties Panel.
Click Create Mesh. A new mesh cabin is created under Built Meshes in the Geometric Entities Panel.
The meshed volume cabin is generated under Volumes.

The mesh created for the fluid domain is shown below.
