class freegs.machine.Circuit(coils, current=0.0, control=True)[source]#

Represents a collection of coils connected to the same circuit

current Current in the circuit [Amps] control Use feedback control? [bool]

__init__(coils, current=0.0, control=True)[source]#: coils - A list [ (label, Coil, multiplier) ]

Methods

`__init__`(coils[, current, control])	coils - A list [ (label, Coil, multiplier) ]
`calcPsiFromGreens`(pgreen)	Calculate psi from Greens functions
`controlBr`(R, Z)	Calculate radial magnetic field Br at (R,Z) due to a unit current
`controlBz`(R, Z)	Calculate vertical magnetic field Bz at (R,Z) due to a unit current
`controlPsi`(R, Z)	Calculate poloidal flux at (R,Z) due to a unit current
`createPsiGreens`(R, Z)	Calculate Greens functions
`from_numpy_array`(value)
`getForces`(equilibrium)	Calculate forces on the coils
`inShape`(polygon)
`plot`([axis, show])	Plot the coils in the circuit Returns the axis used
`psi`(R, Z)	Calculate poloidal flux at (R,Z)
`to_numpy_array`()	Helper method for writing output
