Step 1: Create Geometry in GAMBIT

In an external flow such as the flow past a cylinder, we have to define farfield boundaries and mesh the region between the cylinder geometry and the boundaries. Farfield boundaries should be placed well away from the cylinder so that they are not under the influence of the flow around cylinder.

...

We would like to have more mesh elements at the downstream behind of the flow, to the right of the cylinder. To do accomplish this, we would have to split some edges to create the finer region..

Split the edge according to the figure shown below:
