Dear all,
I'm currently looking for a solution for the problem described in the title. The idea is, that a specific coil geometry (e.g. nTurns, nLayers, conductor radius, ...) leads to different coil parameters (i.e. coil resistance mf.RCoil_1 and coil inductance mf.LCoil_1). I can precompute those values with a stationary study using an arbitrary current (Idc) in the coil excitation field.
For a time-dependent study (in this case frequency transient combining MF and heat transfer) I'd like to use those general parameters. In this case I'd like to assign a time dependent current to the coil excitation: i(t) = u0/mf.RCoil_1 * (1 - exp(t/(mf.LCoil_1/mf.RCoil_1))).
I know that I could e.g. use the withsol operator and rewrite the coil exitation field with the expression for i(t). But as soon as I for exampel to start to change the geometry (add some turns, take away some layers, change conductor radius), the first study would have to be conducted again and I get's cumbersome not forgetting all the steps to get the right result.
Is there any way to solve this? Would it somehow be possible to dublicated the the Coil Node and assign each of the nodes to another studie / studie step?
Thank you very much for your help.
Best,
Stefan
