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.
In this simulation, the flow is turbulent and incompressible. The Segregated Flow model is used together with the default K-Epsilon Turbulence model. The Lagrangian Multiphase model is used to model the dispersed phase.
Only one region for the continuous phase, air, is required for the analysis. By default, the continuum Physics 1 is automatically created when the mesh is imported. Edit the continuum so that appropriate physical models are selected for the air fluid region.
To select the physics models:
