◆ reltol_negative_amounts

double reltol_negative_amounts = -1.0e-14

The relative tolerance for negative species amounts when predicting with first-order Taylor approximation.

When performing a first-order Taylor approximation for the calculation of a chemical equilibrium state, negative amounts of species may result. However, as long as these negative values are small enough, we should not rule out the approximate chemical equilibrium state. This relative tolerance value can be set to control the decision to accept or not the predicted chemical state with negative species amounts. If the accepted predicted equilibrium state has negative amounts of species, these are modified and set to their respective positive lower bounds.
