<DIV>Thanks but that is not quite what I have in mind. The existing PSR model in my CFD code is not converging for PSR models containing the Method of Moments using the ABF mechanism described as shown in the Chemkin 2006 workshop proceedings. I have tried KINSOL and have still not been able to get it to converge. Any assistance in developing a PETSC based solution algorithm is appreciated.</DIV>
