Hello All
I am doing a simple tube methane combustion simulation using Laminar Finite Rate combustion model. The tube is 8.5m by 0.08m in 2D. I patched 9.5% methane to the filled zone and ignited it by ignition model. The initial time step size is 0.001s and set as adaptive.
The problem is, after I run the calculation, the TUI always give me something like:
temperature limited to 2.300000e+03 in 93 cells on zone 2 in domain 1

in the flame zone and the continiuty residue went up to very high value and soon got diverged.

Anybody can help me out??

Thank you very much!!!!!!
