    Hello Natto,

    Actually, it really depends on your application definition. In a general way, resistances in stranded coil conductor components associated to face/volume regions are automatically evaluated during resolution taken into account coil area, length, material resistivity at working conditions, fill factor and number of turns  (see image).

    Additionally, specific simulations can be performed to estimate resistance in working conditions (temperature and current distribution may play a major role in resistance values). Since you will obtain all electrical values you can evaluate real resistance during postprocessing.

    Anyway, for most of applications, a critical variable for coil resistance calculus is the fill factor that is mostly estimated through practical measures.

    Best regards,

    Alejandro
