Default Divergence in conjugate heat transfer calculation

Hi,

I perform a simulation of n-heptane combustion within cylindrical combustion chamber. Combustion itself works well, but when I swiched on the conjugate heat transfer calculation, the calcuation diverges after the 1st iteration (mass and dissipation residuals are of order 1e+20). I've tried to set low under-relaxation factors, but it doesn't help... Any ideas?

Thanks in advance,

Julie

A good idea would be to check your mesh again because it could be a main cause of divergence. It seems that there is another source of inlet. Check your boundaries also
