It is a versatile electromagnetic design tool as it calculates the magnetic and electric field and flux, electric potential, voltage, current, magnetic force, electric force, torque, eddy current and losses, resistance, inductance, capacitance, skin effect, proximity. To see the results of the DC simulation, you go to the Simulate Menu > Annotate DC solution.
