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

Label | Edge Mesh Properties |
A | Interval Count: 36, Double First Length: 0.4667 5 |
B | Interval Count: 36, Double First Length: 0.1867 2 |
C | Interval Count: 30, First Length: 0.129 1 |
D | Interval Count: 18 |
E | Interval Count: 90, First Length: 0.1 |
F | Interval Count: 36 |
G | Interval Count: 72 |
H | Interval Count: 30 |
I | Interval Count: 36, Double First Length: 0.04667 05 |
Operation Toolpad > Mesh Command Button > Edge Command Button > Mesh Edges
Select the edge AB. The edge will change color and an arrow will appear on the edge. This indicates that you are ready to mesh this edge. Select interval size under Spacing. Enter 0.04 for interval size.
Next we will mesh the edge BC. Select the edge BC and enter 0.04 for interval size.
Do the same for edge CD and CF.
Mesh edge 'A' through 'I' according to the properties shown on the table.
After we have all the edge meshes, we can mesh the facesNow that the appropriate edge meshes have been specified, mesh the face face1:
Operation Toolpad > Mesh Command Button > Face Command Button > Mesh Faces
Select the face1. The face will change colorface one by one. You can use the defaults of Quad (i.e. quadrilaterals) and Map. Click Apply.
The meshed face should look as follows:

Next mesh face face2 in a similar fashion.
The resultant mesh should look as follows:
