Detailed Description

1D linearly interpolated plasma

Plasma data which is defined in a 1D uniform grid from which the values are interpolated linearly. The coordinate is the normalized poloidal flux.

Function Documentation

plasma_1D_init_offload()

int plasma_1D_init_offload	(	plasma_1D_offload_data *	offload_data,
		real **	offload_array )

Initialize 1D plasma data and check inputs.

Before calling this function, the offload struct is expected to be fully initialized.

The offload array is expected to hold plasma data as

• [0] = rho grid
• [n_rho] = electron temperature [J]
• [n_rho*2] = ion temperature [J]
• [n_rho*2 + n_rho*n_ions] = electron density [m^-3]
• [n_rho*2 + n_rho*n_ions + n_rho] = ion density [m^-3]

Since this data requires no initialization, the only thing this function does is that it prints some values as sanity check.

Parameters

offload_data	pointer to offload data struct
offload_array	pointer to pointer to offload array

Returns

zero if initialization succes

plasma_1D_free_offload()

void plasma_1D_free_offload	(	plasma_1D_offload_data *	offload_data,
		real **	offload_array )

Free offload array and reset parameters.

This function deallocates the offload_array.

Parameters

offload_data	pointer to offload data struct
offload_array	pointer to pointer to offload array

Definition at line 97 of file plasma_1D.c.

plasma_1D_init()

void plasma_1D_init	(	plasma_1D_data *	pls_data,
		plasma_1D_offload_data *	offload_data,
		real *	offload_array )

Initialize magnetic field data struct on target.

This function copies the magnetic field parameters from the offload struct to the struct on target and sets the plasma data pointers to correct offsets in the offload array.

Parameters

pls_data	pointer to data struct on target
offload_data	pointer to offload data struct
offload_array	pointer to offload array

Definition at line 114 of file plasma_1D.c.

plasma_1D_eval_temp()

a5err plasma_1D_eval_temp	(	real *	temp,
		real	rho,
		int	species,
		plasma_1D_data *	pls_data )

Evaluate plasma temperature.

This function evaluates the temperature of a plasma species at the given radial coordinate using linear interpolation.

Parameters

temp	pointer to where evaluated temperature [J] is stored
rho	radial coordinate
species	index of plasma species
pls_data	pointer to plasma data struct

Returns

zero if evaluation succeeded

Definition at line 145 of file plasma_1D.c.

plasma_1D_eval_dens()

a5err plasma_1D_eval_dens	(	real *	dens,
		real	rho,
		int	species,
		plasma_1D_data *	pls_data )

Evaluate plasma density.

This function evaluates the density of a plasma species at the given radial coordinate using linear interpolation.

Parameters

dens	pointer to where evaluated density [m^-3] is stored
rho	radial coordinate
species	index of plasma species
pls_data	pointer to plasma data struct

Returns

zero if evaluation succeeded

Definition at line 185 of file plasma_1D.c.

plasma_1D_eval_densandtemp()

a5err plasma_1D_eval_densandtemp	(	real *	dens,
		real *	temp,
		real	rho,
		plasma_1D_data *	pls_data )

Evaluate plasma density and temperature for all species.

This function evaluates the density and temperature of all plasma species at the given radial coordinate using linear interpolation.

Parameters

dens	pointer to where interpolated densities [m^-3] are stored
temp	pointer to where interpolated temperatures [J] are stored
rho	radial coordinate
pls_data	pointer to plasma data struct

Returns

zero if evaluation succeeded
