This lesson covers the process of setting up the Ansys Fluent® fluid simulation software solver. It explains how to define governing equations, add boundary conditions, and select the precision level. The lesson also discusses how to adjust solver processes to match the number of CPU cores for effective parallelization. It provides a step-by-step guide on how to perform a mesh check, refine governing equations, apply gravitational acceleration, and alter the governing equations. The lesson further explains how to specify material properties and boundary conditions, and how to define the boundary conditions for the inlet and outlet.
