Physics Setup

Launch FLUENT

We will be working within ANSYS Workbench. To launch FLUENT, double click on the Setup cell from the Project view. Make sure the Double Precision option is selected. This will use 64 bits (rather than 32) per floating point number, decreasing round-off errors.

Recall that you can look at specific components of the mesh by choosing the entities you wish to view under Surfaces (click to select and click again to deselect a specific boundary). Click Display again when you have selected your boundaries. Use this feature and make sure that the boundary labels correspond to the correct geometric entities.

This completes the boundary condition specification.

Reference Values

Let's setup the reference values, which will be used later on while while viewing non-dimensional results (this setting doesn't affect the numerical solution).
