Hello, Ozan,
For larger mechanisms Chemkin-CFD solver tends to be faster.Â
Usually you do not change anything for ISAT except the ISAT error tolerance. You should keep the default value of 0.001 initially and reduce the error tolerance only after a reasonably converged solution has been obtained. After reducing the ISAT error tolerance, re-converge the calculation. This process should be repeated until changes in quantities of interest are acceptable.Â
