After fitting a medium, as described here, it is possible to save the fitted medium as an hdf5 file and save time when using it in another model. To save the file, just use the .to_file method:

fitted_medium.to_file('medium_name.hdf5')

Now, the saved medium can be loaded with the PoleResidue .from_file method:

loaded_medium = td.PoleResidue.from_file('medium_name.hdf5')

To use this medium via the web GUI, you have two options:

(a): open the “Material Utilities”, select the “Private Library”, and click the “Upload Material” button;

(b): in the workbench, create a new medium and choose the “Import Material” option in the “Add Medium” panel.
