Error: ISAT reaction rate
I am trying to simulate combustion with Steady Laminar Flamelet model (Non-premixed model in fluent). I did it with some mechanisms like GRI3.0 with no problem. but for some other reaction mechanisms I face this problem:
I read the mechanism in CHEMKIN format into Fluent and when I want to develop the flamelet, I get this error:
Error: ISAT reaction rate: Temperature = -3325385810.5K
Error Object: ()
I can bypass this problem by changing the relative error tolerance in Integration control form e-10 to e-17 but the accuracy of result is lowered and it seems I am just getting some "Garbage in/Garbage out". does any one have an idea about the source of problem?
thank you in advance for sharing your thoughts.
if you obtain answer your question,please guide me
Unfortunately I couldn't solve the problem... :(
