Chemistry ODE Solver in reactingFoam
 

I was just wondering about the meanings of the settings in the edoCoeffs dictionary:

odeCoeffs
{
solver SIBS;
eps 0.05;
scale 1;
}

'solver' I know chooses between different methods (RK, KRR4, and SIBS are the only three I know of that OpenFOAM can use). However, I don't know what 'eps' and 'scale' are used for here. Any help?

Thank you.

eps is the tolerance for convergence (the difference between successive timesteps before you accepts the answer) and scale is a multiplication factor for the time stepping (which can speed up convergence depending on your ODE.
