Hello,
I am trying to simulate ignition delay of n-decane in ChemKin Pro (Closed homogeneous model) using this mechanism (DOI: 10.1021/acs.energyfuels.6b02186) but it fails to run every time with the following error; TASK INTERRUPTED: TROUBLE IN THE TRANSIENT SOLVER DDASPK THE MATRIX OF PARTIAL DERIVATIVES MAYBE SINGULAR Any help in dealing with this error would be appreciated. Thank you  Regards, MRaza |

Use Legacy Solution Setting In Solver. In encountered when I included heat loss from wall using convective coefficient, thermal mass.
