Mesh xy cross-section of component at height z.

Parameters:

  • component (Component) – gdsfactory component to mesh

  • z (float) – z-coordinate at which to sample the LayerStack

  • layer_stack (LayerStack) – gdsfactory LayerStack to parse

  • layer_physical_map – map layer names to physical names

  • layer_meshbool_map – map layer names to mesh_bool (True: mesh the prisms, False: don’t mesh)

  • resolutions (Dict) – Pairs {“layername”: {“resolution”: float, “distance”: “float}} to roughly control mesh refinement

  • default_characteristic_length – default characteristic length for the mesh

  • background_tag (str) – name of the background layer to add (default: no background added)

  • background_padding (Tuple) – [xleft, ydown, xright, yup] distances to add to the components and to fill with background_tag

  • background_mesh_order (int, float) – mesh order to assign to the background

  • global_scaling – scaling factor for the mesh

  • global_scaling_premesh – scaling factor for the mesh before meshing

  • global_2D_algorithm – gmsh 2D algorithm to use

  • filename (str, path) – where to save the .msh file

  • verbosity – verbosity level for gmsh

  • round_tol – during gds –> mesh conversion cleanup, number of decimal points at which to round the gdsfactory/shapely points before introducing to gmsh

  • simplify_tol – during gds –> mesh conversion cleanup, shapely “simplify” tolerance (make it so all points are at least separated by this amount)

  • n_threads – number of threads to use for mesh generation

  • port_names – list of port names to mesh

  • gmsh_version – gmsh version to use

  • interface_delimiter – delimiter to use for new layers generated for interfaces: “layer{interface_delimiter}interface_name”.

  • layer_port_delimiter – Delimiter to use for new layers generated for ports: “layer{delimiter}port_name”.

  • background_remeshing_file – filename to load background remeshing from.

  • optimization_flags – flags for Model.mesh

  • kwargs – kwargs for Model.mesh
