Function/Subroutine Documentation

faraday()

subroutine siesta_bfield::faraday	(		djbsupsmnh,
			djbsupumnh,
			djbsupvmnh
	)

Use Faraday's law dB = -curl(E) to compute magnitic field perturbation.

The arrays must be passed in as ALLOCATABLE to preserve the array bounds.

Parameters

[in,out]	djbsupsmnh	Contravariant displacement in the s direction.
[in,out]	djbsupsmnh	Contravariant displacement in the u direction.
[in,out]	djbsupsmnh	Contravariant displacement in the v direction.
[in]	esubsijf	Covariant real space electric field in the s direction.
[in]	esubuijf	Covariant real space electric field in the s direction.
[in]	esubvijf	Covariant real space electric field in the s direction.
[in]	parity	Fourier parity control flag.
[in]	nsmin	Minimum radial index.
[in]	nsmax	Maximum radial index.

update_bfield()

subroutine siesta_bfield::update_bfield

(

logical, intent(in)

l_add_res

)

Update contravariant componets of the magnetic field.

Advances half-mesh magnetic field components in nm space from time t to t + dt. Used to update values of bsup*mnh and bsupijh stored in the quantities module. Discretized version of Faraday's law

dB/dt = -Curl(E) (1)

Parameters

[in]

l_add_res

Control flag to add resonant field.
