2D meshing: xy cross-section#
You can supply the argument type="xy" and a z-value, to mesh arbitrary Component planar cross-sections.

def mesh_with_physicals(mesh, filename):
mesh_from_file = meshio.read(f"{filename}.msh")
return create_physical_mesh(mesh_from_file, "triangle")
At z=0.09 um, according to the layer stack above we should see polygons from all three layers:
filename = "mesh"
mesh = get_mesh(
component=waveguide,
type="xy",
z=0.09,
layer_stack=filtered_layer_stack,

Controlling meshing domain#
You can use functions that return other components to modify the simulation domain, for instance gdsfactory.geometry.trim:
waveguide = gf.components.straight_pin(length=11, taper=None).dup()
waveguide.trim(left=3, right=5, bottom=-4, top=4)
waveguide
mesh = get_mesh(
component=waveguide,
type="xy",
z=0.09,
layer_stack=filtered_layer_stack,
filename=f"{filename}.msh",
