Detailed Description

1D spline electric field evaluation functions

Radial electric field evaluated from 1D profile. Exactly as E_1D but the potential is evaluated with splines.

Function Documentation

E_1DS_init()

int E_1DS_init	(	E_1DS_data *	data,
		int	nrho,
		real	rhomin,
		real	rhomax,
		real	reff,
		real *	dvdrho )

Initialize 1DS electric field data.

Parameters

data	pointer to the data struct
nrho	number of points in the rho grid
rhomin	minimum rho value in the grid
rhomax	maximum rho value in the grid
reff	effective minor radius
dvdrho	gradient of the potential

Returns

zero if initialization succeeded

Definition at line 29 of file E_1DS.c.

E_1DS_free()

void E_1DS_free

(

E_1DS_data *

data

)

Free allocated resources.

Parameters

data	pointer to the data struct

Definition at line 58 of file E_1DS.c.

E_1DS_offload()

void E_1DS_offload

(

E_1DS_data *

data

)

Offload data to the accelerator.

Parameters

data	pointer to the data struct

Definition at line 67 of file E_1DS.c.

E_1DS_eval_E()

a5err E_1DS_eval_E	(	real	E[3],
		real	r,
		real	phi,
		real	z,
		E_1DS_data *	Edata,
		B_field_data *	Bdata )

Evaluate 1D spline radial electric field.

This function evaluates the 1D spline potential gradient of the plasma at the given radial coordinate using linear interpolation, and then calculates the radial electric field by multiplying that with the rho-gradient. Gradient of rho is obtained via magnetic field module.

Parameters

E	array where the electric field will be stored (E_r -> E[1], E_phi -> E[1], E_z -> E[2])
r	R-coordiante [m]
phi	phi-coordinate [rad]
z	z-coordiante [m]
Edata	pointer to electric field data
Bdata	pointer to magnetic field data

Returns

zero if evaluation succeeded
