The overall boundary is shown below.

 
Where ABCDE is the farfield boundary and FE is the wedge.

 Using Using bottom up approach, we start by creating vertices of the geometry using the coordinate given.

Operation Toolpad > Geometry Command Button Image Added> Vertex Command Button Image Added> Create VertexVertex  Image Added

Create the vertices by entering the coordinates under Global and the label under Label:

Click the FIT TO WINDOW button to scale the display so that you can see all the vertices.  The resulting image should look like this:

Create Faces

Now we can create the edges using the vertices created.

Operation Toolpad > Geometry Command Button Image Added> Edge Command ButtonButton  Image Added> Create Edge Image Added

Create the edge AB by selecting the vertex A followed by vertex B. Enter AB for Label. Click Apply. GAMBIT will create the edge. You will see a message saying something like "Created edge: AB'' in the Transcript window.

Similarly, create the edges BC, CD, DE, EF, FA and CF. Click on the  to the  Image Added to select the vertices from the list and move them to the picked list. You can also hold the shift button and mouse click the vertices for selection.The resulting image should look like this.

Create Faces

The edges we have created can be joined together to form faces. We will need to define two faces.

Operation Toolpad > Geometry Command Button Image Added> Face Command Button Image Added> Form Face Image Added

This brings up the Create Face From Wireframe menu. Recall that we had selected vertices in order to create edges. Similarly, we will select edges in order to form a face.

We will call two faces face1 and face2. To create the face1, select the edges AB, BC, CF, and FA. Enter face1 for the label and click Apply. GAMBIT will tell you that it has "Created face: face1'' in the transcript window.
