Selecting the Physics Models

Physics models define the primary variables of the simulation, including pressure, temperature, velocity, and what mathematical formulation is used to generate the solution.

The main phenomena to solve for in this simulation is unsteady, laminar, incompressible, gaseous flow. Set up an implicit unsteady, laminar, incompressible, gaseous flow using the segregated flow and fluid film models.

To select the physics models:

  1. For the physics continuum, Continua > Physics 1, select the following models in order:
