Step 3: Specify Boundary Types in GAMBIT
We'll label the boundary ABCDE as farfield, EF as wedge and AF as symmetry. Recall that these will be the names that show up under boundary zones when the mesh is read into FLUENT.
Group Edges
We'll create groups of edges and then create boundary entities from these groups.
First, we will group AB, BC, CD and DE together.
...
Group Name | Edges in Group |
farfield | AB,BC,CD,DE |
wedge | EF |
symmetry | EF |
Define Boundary Types
Now that we have grouped each of the edges into the desired groups, we can assign appropriate boundary types to these groups.
...
Similarly, create boundary entities corresponding to farfield and symmetry groups. Set Type the to Pressure Farfield and symmetry in each case.
