Hi!
How can we make the FDTD simulations match lumerical FDTD?
Im running tidy3d-beta==1.4.0
See Sparameters for a 1x2 mmi in tidy3d

Hi,
Convert the polygon in the layout to .svg seems to be achieved by the following code, but the svg file and port appearing in interconnect are mismatched. Why?

[here](https://gdsfactory.github.io/gdsfactory/notebooks/plugins/lumerical/1_fdtd_sparameters.html) it says

some functions, like meep and tidy3d write sparameters assume the o1, o2, o3 ... port names.it would be great to enable other port naming conventions.
Here are some other port conventions
