Setting Up the Models
Models define the primary variables of the simulation, including pressure, temperature, velocity, and what mathematical formulation is used to generate the solution. In this example, the flow is laminar and incompressible.
The Segregated Energy model is used together with the Surface-to-Surface Radiation model to determine the temperature field.
As there are two materials (air and glass) present, two regions are required for the analysis. You define two sets of Physics continuum models, each appropriate to a different region. By default, and are automatically created when the mesh is imported. You use these continua for the fluid and the solid.
