The final stage of a CFD study is to explain what the results support. Bring together the physical assumptions, numerical checks, and flow observations to produce a clear engineering conclusion.…

Post-processing helps you inspect the solution and communicate its physical meaning. A useful figure identifies the field being shown, its units, its location, and any reference-frame choices needed to interpret…

Introduction Once the environment, case settings, and mesh have been checked, you can run the simulation. The next responsibility is to determine whether the numerical solution has converged sufficiently for…

Introduction The mesh divides the fluid domain into the cells on which the equations are solved. Its geometry, connectivity, and resolution influence numerical stability and the flow features the calculation…

Introduction An OpenFOAM case is a structured description of a physical problem and the numerical method used to solve it. Understanding that structure allows you to explain the simulation, modify…

Introduction A reproducible simulation starts with a reproducible software environment. Before running the starter, confirm that your operating system, OpenFOAM installation, and supporting tools match its documented requirements. Learning objective…

Introduction A rotating machine transfers energy between a rotor and a fluid. To simulate that process, we need a model that accounts for rotation. The Multiple Reference Frame approach, or…
