Ansys Maxwell Transformer Transient Simulation Error

      I'm modeling the transformer shown below, with an applied voltage of 600*cos(2*pi*100000*time). I have assigned the primary winding resistance to 1mOhm and the secondary winding resistance to 200Ohms, and would except the secondary induced voltage to be 600*(10/3) = 180V with no phase shift. When I run a transient simulation, however, this is not the case, and my results are are shown below. I am using ferrite for the core, copper for the windings, and have created a region of air around the transformer. I also have length-based assigned mesh operations for the primary and secondary windings, with the max length set at 11mm. My coil terminals and excitations can also be seen in images below. Any help would be greatly appreciated!

      Hello,nI'm moving this discussion to the Electronics sub-category for better alignment. Also, as Ansys employees, we are not able to download attachments from the Learning Forum. Could you please embed these images directly to your post?nThanks.nKarthikn

      nWe are not allowed to click on non-displaying images, next time please choose attach image rather than attach file. nFrom your description, I think you probably assigned 1mohm and 200ohm to R in the winding window. In order to make InducedVoltage(winding2)=600*(10/3) = 180V, try the following. First, change 1mohm to 0.01 uohm for primary winding. At the same time, make the secondary winding open (set I=0 or set R to a very large number 200 ohm is not large enough).n
