Hi Anushka,

HFSS is an Electromagnetic Solver which solves Maxwell's equations to obtain electromagnetic solutions for a given geometry and boundary conditions. Maxwell's equations are a set of four partial differential equations that describe the behavior of electric and magnetic fields and their interactions with matter.

The surface current is mathematically extracted from the calculated H field.

You can find  more information on the calculated Field Quantities of HFSS in the following link of HFSS Help,
