Hello all,
I want to use TDAC method in my combustion simulation.
But I face with a message saying:
Badly Conditioned rAB : 1species involved : 11,1


This message is defined in thermophysicalModels/chemistryModel/TDACChemistryModel/reduction/DAC/DAC.C


and the rAB is defined in thermophysical Models/chemistryModel/TDACChemistryModel/reduction/DAC/DAC.H


Can anyone tell me what is this message about and how can I solve it?
Thanks in advance
