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.
