Detailed Description

Struct representing NSIMD guiding center markers.

This struct is used in simulation when the simulation loop in simulate_gc_fixed.c or simulate_gc_adaptive.c is used.

It contains physical and simulation parameters necessary for the simulation If a function makes changes to any of these parameters, it is that function's responsibility to make sure all fields remain consistent, i.e., if position changes then the magnetic field should be updated. Each field is a memory aligned array with length NSIMD, so this struct represents NSIMD markers (they can be dummy or markers whose simulation has been terminated) and so it can be used within SIMD loops.

The fields are aligned to 64 bit with memalign (see ascot5.h).
