Methane Ignition simulation in a 2D combustion chamber

      Hello,
      I am simulating methane combustion in a 2D rocket chamber. The energy deposition is done on a small kernel area and the k-omega model with SBES enabled is used. While processing the results, if I plot contours of temperature and velocity, I get the following images.
      I have also attached images of the model settings and the expression of my energy source. 
      My objective is to get ignition and the expected contour is also attached as an image. All my parameters seem correct, but I do not get a temperature contour field. I am not sure why. It would help if I can receive some feedback.

      How does convergence look?

      I have imported a reduced chem-kin mechanism for methane combustion. I get a floating point exception towards the end of my solution.

      That's diverged, so most likely there's a problem with mesh or set up.
