Edges | Name |
A | farfield 1 |
B,C | farfield 2 |
D,E | farfield 3 |
E,G,H | farfield 4 |
I,J | cylinder |
...
Group Edges
Group the appropriate edges accordingly.
Operation Toolpad > Geometry Command Button > Group Command Button > Create Group
Select Edges and enter farfield1 for Label, which is the name of the group. Select the edges AF and EF.
Note that GAMBIT adds the edge to the list as it is selected in the GUI.
Click Apply.
In the transcript window, you will see the message "Created group: farfield1 group".
Similarly, create the other two farfield groups. You should have created a total of three groups:
Group Name | Edges in Group |
|---|---|
farfield1 | AF,EF |
farfield2 | AB,DE |
farfield3 | BC,CD |
airfoil | HI,IG,HJ,JG (name might vary) |
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.
Operation Toolpad > Zones Command Button 
> Specify Boundary Types 
Under Entity, select Groups.
Select any edge belonging to the airfoil surface and that will select the airfoil group !btype_cb.jpg|width=32,height=32!Specify boundary according to the table above. Next to Name:, enter airfoilthe name accordingly. Leave the Type as WALL.
Click Apply.
In the Transcript Window, you will see a message saying "Created Boundary entity: airfoil".
Similarly, create boundary entities corresponding to farfield1, farfield2 and farfield3 groups. Set the Type to Pressure Farfield in each case.We will specify boundary type using FLUENT.
