Numerical Solution — Lesson 6

This lesson covers the process of using Ansys Fluent® fluid simulation software to solve mathematical models, it explains how Ansys Fluent determines the primary unknowns at the cell centers and how to specify other quantities to be calculated from these values. The lesson also discusses how to add the drag coefficient to the report and how to calculate it from the pressure values in the solution. The lesson further explains how to specify reference values and how to solve the mathematical model iteratively to get the cell center values of the primary unknowns. The lesson concludes with how to begin the iterative process, set initial guest values for the primary unknowns in each cell, and how to ensure the solution has converged.
