Hello everyone
I am trying to simulate flame propagation of methane oxygen mixture in a tube and i am nearly done... the only problem is that the wall heat flux at the center of the tube has negative (which is normal) BUT also positive values (which does not make any sense...) through time. CAN ANYONE HELP ME??????

thank you very much
kind regards
