Can speed up experiments utilizing CRESP where spectral timesteps are much shorter than timesteps for fluid components.
Allows substepping in spectrum update: state of each cell is separately updated in a loop of n_substeps by dt_substep=dt / n_substeps, allowing to ignore spectral timestep when choosing shortest for global domain update.
