Calculate loss in Maxwell 2D or 3D (Ansoft)

Hi, everyone,

I am using Maxwell 2D&3D from Ansoft to do transformer design. I can use it to plot different figures, such as energy distribution, H field, current density and so on, but I don't know how to calculate loss (copper loss and core loss). Do you know how to do this?

Thank you very much!
