August undefined, 2024

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.

"WebThe AMR library of OpenFOAM® can only be used for 3D cases The training case provided by Tobias Holzmann takes the adaptive (automatic) mesh refinement into account. However, due to the fact that OpenFOAM® does not offer a 2D adaptive mesh refinement, this case is a pseudo-2D case. " - Openfoam 2d mesh to 3d
