* init Initialize matrices etc. for circuit.

init(this, problem) ties this to the given MagneticsProblem and initializes the problem matrices and arrays in this.matrices:

  • inds_solid : which of the Conductors in this are solid

  • inds_stranded : likewise for stranded

  • R : per-conductor resistances, active length

  • R_EW : per-conductor resistances, end-winding length

  • area : conductor areas

  • sigma : conductor conductivities. Assumed uniform.

  • M : mass/damping matrix

  • C_Ai : current source matrix

  • C_Au : voltage source matrix

  • C_uu : voltage-voltage coupling matrix

  • L : circuit loop matrix Help for LaminatedCircuit/init is inherited from superclass CIRCUIT

* TODO fix plotting etc
