SubscriberI am not yet familiar with this software and would like to ask a question.
The magnetic material wraps around the non-magnetic material, both of which are cylindrical. An AC voltage is applied, but I am unsure how to apply the AC voltage, so I have set it as DC instead.
If my company only calculates ohmic loss, do I need to account for core loss as well?
Or, aside from ohmic loss, are there other factors that should be considered?Â

Ansys EmployeeHi, you can apply an AC voltage in eddy current and time transient magnetic solvers by creating a winding.
Ansys Electronics 2023 R2 - 2D Eddy Current Excitations

Ohmic losses, as you mentioned, are related to the resistance of the conductors and can be calculated using Maxwell to include effects such as induced steady current losses in permanent magnets, rotor bars, or stator windings, as well as eddy losses. Core losses, on the other hand, are associated with the magnetic material of the core and include hysteresis and eddy current losses within the core material itself.
I hope this helps!
