Hi, I'm trying to run a case with an inlet of pure methane at 300k combusting in 1500k coflowing air. I run the case without chemistry for 2000 iterations, and then enable chemistry where it runs for I think 12 more iterations before crashing.

This is the output from the log files when it crashes. I'm still relatively new to OpenFOAM, and so I wondered if there is something I'm doing wrong that's glaringly obvious.

Thanks.
