We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

      In ANSYS Fluent, when density is modelled using ideal gas law, it is recommended to use an operating density value of zero. In such cases, users need to be careful in setting up boundary conditions for pressure outlets/inlets. In natural convection cases, where minor density differences (due to temperature variations) cause the flow, choosing the right operating density would be important for good convergence. This documents provides guidelines in choosing the best operating density values for such cases using an example.
