llg-heun-gpu

Solves the Landau-Lifshitz-Gilbert (LLG) equation using the Heun integration method on a GPU.

Note

JAMS must be build with CUDA supprot and the computer must have an NVIDIA GPU supporting CUDA available.

Required settings

t_step

Integration time step in seconds. Usually \(1\times10^{-16}\mathrm{s}\) is sufficient.

t_max

Maximum integration time in seconds. It can be stopped early by a converged monitor.

Optional settings

t_min

Minimum integration time in seconds. Solver will continue to this time even if a monitor has converged.
