Function Documentation

step_gc_rk4()

void step_gc_rk4	(	particle_simd_gc *	p,
		real *	h,
		B_field_data *	Bdata,
		E_field_data *	Edata )

Integrate a guiding center step for a struct of markers with RK4.

This function calculates a guiding center step for a struct of NSIMD markers with RK4 simultaneously using SIMD instructions. All arrays in the function are of NSIMD length so vectorization can be performed directly without gather and scatter operations.

Parameters

p	simd_gc struct that will be updated
h	pointer to array containing time steps
Bdata	pointer to magnetic field data
Edata	pointer to electric field data

step_gc_rk4_mhd()

void step_gc_rk4_mhd	(	particle_simd_gc *	p,
		real *	h,
		B_field_data *	Bdata,
		E_field_data *	Edata,
		boozer_data *	boozer,
		mhd_data *	mhd )

Integrate a guiding center step with RK4 with MHD modes present.

Same as previous function but with MHD present

Parameters

p	simd_gc struct that will be updated
h	pointer to array containing time steps
Bdata	pointer to magnetic field data
Edata	pointer to electric field data
boozer	pointer to boozer data
mhd	pointer to MHD data
