We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Hello, Ozan,

For larger mechanisms Chemkin-CFD solver tends to be faster. 

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.
