Electric field just above an interface

Somewhere in the air gal I place a square dielectric. I notice the solved E field is discontinuous at the air-dielectric interface. So it's a different value just inside and just outside the dielectric.
Now I want to plot the E field along one of the edges of the dielectric, just inside or just outside it. I could draw another slightly larger or smaller box around it, and plot E along the edge of this new box, but that tends to mess up my meshing, and I won't get the true boundary values that way. Is there a better way?

I would recommend to search in the COMSOL documentation.

"evaluate variable on side of boundary"
"plot one side of boundary"
"COMSOL operator to evaluate variables on a specific side of a boundary"
...?
These search terms are returning too many false positives.. Can you please tell me the operator name so I can go straight to it?
