Hi @sampathkumar,
You could use stranded loss, however, AC effect is not considered. If you use Litz wire model in your material of the winding, you could use StrandedLossAC.
• StrandedLoss is dependent on the object’s material conductivity of a stranded source. It represents the loss due to the DC resistance only and uses the cross-sectional area of the object that is assigned with the excitation. Where J is the current density, it is calculated by:
o When Litz wire is not defined, StrandedLoss is computed by assuming fill factor = 100% (the ratio of net conductor area to coil terminal area).
o When Litz wire is defined, StrandedLoss is computed by using the actual fill factor based on the specified Litz stranding and represents the DC loss only.
o StrandedLoss does not include the losses of end-coil resistance in 2D.
o StrandedLoss can be used to scale the loss density to a coupled thermal analysis.
• StrandedLossAC is reported when using Litz wire model, and is dependent on the object’s material conductivity of a stranded source. It represents the loss due to the DC resistance as well as AC eddy current losses due to proximity effects and skin effects.
o StrandedLossAC = StrandedLoss + AC eddy current losses due to proximity effects and skin effects.
o StrandedLossAC does not include the losses of end-coil resistance in 2D.
o StrandedLossAC can be used to transfer loss density to a coupled thermal analysis.
• StrandedLossR represents the loss based on I2 times the resistance R, by using the resistance value entered in the Winding properties for a voltage type winding only (Reported for a stranded voltage source not in an external circuit).
