3D Magnetic Vector Potential
Posted: 07 Feb 2018, 15:40
Hi!
I am working on a project which requires the calculation of the mutual inductance between two coils (one arbitrarily shaped coil to be tested and a circular probe coil (which can be moved to different positions)). My idea was to use the MagnetoDynamicsCalcFields solver to calculate the magnetic vector potential of the arbitrarily shaped coil only and do some further calculations with the computed field in a python script. I attached the main mathematical formulation of the way I plan to calculate the mutual inductance below. I_1 is the current flowing through the arbitrary coil, A is the calculated magnetic vector potential, Gamma_2 is the path following the shape of the circular probe coil (which I can move in the python script), t is the tangent vector of this path. I already wrote the python script to do this calculation based on the node/vector data provided by the ElmerPost file of the mgdyn_torus example (which I only wanted to slightly modify to support my coil designs). But by reading the Keyword section of "Model 15: Computation of Magnetic Fields in 3D" of the Elmer Models Manual I realized that neither the WhitneyAVSolver nor the MagnetoDynamicsCalcFields are using the magnetic vector potential. Instead they use the scalar magnetic potential. So my question is: Is there any way to calculate the magnetic vector potential (3D) produced by a coil using one of the solvers provided by Elmer?
Kind regards,
Julius
