Step 2: Mesh Geometry in GAMBIT
Mesh Edges
Before we mesh the faces, we should mesh the edges so that we can better define the mesh.
Following figure shows the edges with different mesh properties.

Operation Toolpad > Mesh Command Button 
> Edge Command Button 
> Mesh Edges 
Mesh edge 'A' through 'I' according to the properties shown on the table.
After we have all the edge meshes, we can mesh the faces:
Operation Toolpad > Mesh Command Button 
> Face Command Button 
> Mesh Faces 
Select the face one by one. You can use the defaults of Quad (i.e. quadrilaterals) and Map. Click Apply.
The meshed face should look as follows:
