WebAs you know, in OpenFOAM if we want to do a 2D simulation we create a 3D mesh with at least one cell thick in the third dimension and specifying it as empty Boundary condition. IMO, it is more natural to have a tool or at least adding some options to the existing foamToFluentMesh utility to convert these 2D meshes to 2D mesh for Ansys Fluent.
