MAGNETO has the ability to input a magnetic loss curve in the Material Table and then assign the material to the model’s geometry. The magnetic loss curve combines hysteresis loss and lamination loss (eddy current losses in the laminations) information. These loss curves are available from the material supplier.
The software requires that you place subareas in regions with lossy materials for the total loss calculation to solve the loss density over the entire region. If you are only interested in power loss density, you can leave the subareas out.
