There are different methods in creating geometry. The most fundamental approach in creating geometry is the bottom-up vertical hierarchy approach. We will start with first creating vertices, then connecting the vertices to form edges, and finally connect the edges to form faces. Note that in 3D problems, you'll have to form a "volume" from faces. So the hierarchy of geometric objects in GAMBIT is vertices -> edges -> faces -> volumes.

For this tutorial also, be will be using mostly the graphics user interface in creating the geometry.

Create a Working Directory

...

Under Main Menu, select Solver > FLUENT 5/6 since the mesh to be created is to be used in FLUENT 6.0.

Create Vertices

The coordinates needed for the mesh are shown below

First, create vertices with following coordinates:

...

To create a vertex, do the following:

...

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:
