Once, the mesh sizes are specified,the mesh can be generated. To this end, refinement fields defining the mesh sizes within the model have to be calculated and added to the Gmsh model. int32 ) local_entities, local_values = distribute_entity_data ( mesh, mesh. Gmsh mesh creation After the model has been created using the Gmsh-Python-API, the meshing can be performed. We start by specifying a distance field from the obstacle surfaceįrom import AdjacencyList_int32 from import distribute_entity_data from import cell_entity_type, create_meshtags # Create MeshTags for cell dataĬell_values = numpy. One can alternatively set mesh resolutions at points with the command .setSize. The final step is to set mesh resolutions. setPhysicalName ( 2, obstacle_marker, "Obstacle" ) addPhysicalGroup ( 2, obstacles, obstacle_marker ) gmsh. setPhysicalName ( 2, wall_marker, "Walls" ) gmsh. addPhysicalGroup ( 2, walls, wall_marker ) gmsh. ![]() setPhysicalName ( surface, outlet_marker, "Fluid outlet" ) elif np. addPhysicalGroup ( surface, ], outlet_marker ) gmsh.
