Again the geometry for this example is created using the Pre-processor. First we have to create the points with the co-ordinates given below, and then join them into lines (the edges of the control volume).

1. | 0.000000 | 0.000000 | 0.000000 |
2. | 3.000000 | 0.000000 | 0.000000 |
3. | 3.000000 | 3.000000 | 0.000000 |
4. | 0.000000 | 3.000000 | 0.000000 |
Then we create the circle representing the source of a species using the Geometry>Create>Object>Circle utility. The circle has a radius of 0.25m and its centre is at the point (1.000,1.000,0.000).
Finally the external surface of the geometry can be created, by selecting ALL the created lines. The outcome is the final geometry shown in Figure 109.
