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.
