Assigning Parts to Regions

To define the computational domain, assign the parts to regions. In this tutorial, there are two regions, one for each part.

  1. Expand the Geometry > Parts node and multi-select the Fire and Room nodes.
  2. Right-click on one of the selections and choose Assign Parts to Regions....
  3. In the Assign Parts to Regions dialog, select:
    1. Create a Region for Each Part
    2. Create a Boundary for Each Part Surface
  4. Click Apply then Close.
    Two new regions are created with boundaries that define the outlet and the interface between the two regions.
Set the outlet boundary as a Pressure Outlet:
  1. Expand the Regions > Room > Boundaries node.
  2. Select the Outlet node, and set Type to Pressure Outlet.
    In the Graphics window, the surface that corresponds to this boundary changes to an orange color.
