DerivativePhase

enum DerivativePhase

strong

Defines the phases of derivative evaluation.

Derivatives in different phases are evaluated in order, each phase can use results computed by derivatives in previous phase. Order of derivative evaluation within one phase is undefined.

Attention

Phases make only sense for asymmetric evaluation, i.e. if all neighbours are visited for given particles and the computed value is final. For symmetrized evaluation, only a partial value is computed for given particle (and the rest is added when evaluating the neighbouring particles), so the result from previous phase cannot be used anyway!

Enumerator
PRECOMPUTE	Auxiliary quantities needed for evaluation of other derivatives (grad-h, correction tensor, ...)
EVALUATION	Evaluation of quantity derivatives. All derivatives from precomputation phase are already computed and may be used for the computation here.
