About Course

Product Overview

This tutorial demonstrates how to convert Ansys Fluent meshes into OpenFOAM format, enabling you to transfer your mesh from a commercial CFD tool to the open-source environment of OpenFOAM. You’ll learn how to use fluentMeshToFoam and fluent3DMeshToFoam utilities to import complex 2D and 3D mesh files, including multiple regions and boundaries, and prepare them for simulation in OpenFOAM.

This process is essential for engineers and researchers who want to leverage advanced meshing tools like ANSYS Fluent but perform simulations in OpenFOAM.
