## this = LaminatedCircuit(*arguments*) Class for modelling classical eddy currents in

laminated <Domain.html Domain>s.

Modelled with the approach presented in e.g. 'Finite-Element Modeling and Calorimetric Measurement of Core Losses in Frequency-Converter-Supplied Synchronous Machines'.

## this.init(*arguments*) Initialize matrices etc. for circuit.

**init**(*this*, problem) ties *this* to the given MagneticsProblem and *init*ializes 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
