COEFF_dt_d30
time step criterion depending on %ind_d30% (DROPLETPHASE only) (UCV)
COEFF_dt_d30 = 0.5
Default: COEFF_dt_d30 = 0.0 (off)
If a value bigger than zero is specified for this parameter, the timestep criterion
\begin{align} dt\|{\bf v}_i\|= C_{d30} \frac{D_i}{2} \quad \forall i\end{align}
is introduced. This time step criterion is particularly relevant in case DROPLETPHASE interactions are computed.
If this time step criterion leads to a very strong time step restriction, performance can be improved by using COMP_DropletphaseSubcycles.
