Enumerator
INITIAL_VALUE	Timestep is not computed, using given initial value.
MAXIMAL_VALUE	Timestep given by selected maximal value.
DERIVATIVE	Timestep based on value-to-derivative ratio.
CFL_CONDITION	Timestep computed using CFL condition.
ACCELERATION	Timestep constrained by acceleration condition.
DIVERGENCE	Timestep computed by velocity divergence.
MAX_CHANGE	Timestep is limited by the maximum allowed change from previous timestep.
