Recombination of Voxel Transition Cells for OpenFOAM Meshes
Pointwise V18.3 introduced a voxel capability (hex-core) that uses regular hexahedra instead of unstructured tetrahedra in regions away from the geometry model. The space between the final T-Rex (anisotropic tetrahedral extrusion) front and the farfield topology (see Figure 1) is … Continue reading
It’s all in the numbering – mesh renumbering may improve simulation speed
We all know that the mesh plays a vital role in CFD simulations. Yet, not many realize that renumbering (ordering) of the cells in the Finite Volume Method (FVM) can affect the performance of the linear solver and thus the … Continue reading
