Dear all, I have a question about stranded coil conductors using non-meshed coils. I have performed two transient simulations with non-meshed coils in 3D for a transverse flux machine. For the first simulation I entered 100 mOhm in the field "Resistance Formula" of the stranded conductor. For the second simulation I entered 5 mOhm. The geometry as well as the material parameters and number of turns were the same for both simulations. For both simulations, the non-meshed coil was part of an electric circuit. I assumed that the resistance value is calculated via FLUX using the resistance formula R=rho*l/A and that the value entered in the "Resistance Formula" field (stranded coil conductor) does not matter if the specific resistance as well as the fill factor are specified for the non-meshed coil. However, the result for the evaluated resistance is different for both simulations. Preset value of 100 mOhm --> evaluated resistance = 106 mOhm Preset value of 5 mOhm --> evaluated resistance = 11 mOhm The evaluated resistance of the non-meshed coil is the same for both simulations: 3 mOhm. Why is there a difference between the evaluated value of the non-meshed coil and of the stranded conductor? I assumed, this should be the same? Therefore, could you please tell me, how the evaluated resistance of the stranded coil conductor is determined? Is it important, to enter the "right" value in the field "resistance formula"? Thank you in advance and best regards, Mandy
