Function Documentation

◆ step_ml_cashkarp()

void step_ml_cashkarp	(	particle_simd_ml *	p,
		real *	h,
		real *	hnext,
		real	tol,
		B_field_data *	Bdata )

Integrate a magnetic field line step for a struct of markers.

This function calculates a magnetic field line step for a struct of NSIMD markers with Cash-Karp (adaptive RK5) simultaneously using SIMD instructions. All arrays in the function are of NSIMD length so vectorization can be performed directly without gather and scatter operations. Informs whether time step was accepted or rejected and provides a suggestion for the next time step.

Parameters

p	marker struct that will be integrated
h	NSIMD length array containing time step lengths
hnext	suggestion for the next time step. Negative if rejected.
tol	error tolerance
Bdata	pointer to magnetic field data
