The temperature is constant at 5000K. What you are seeing is colours based on the round-off error around that number.

For some reason, the temperature field has not been solved. Possible reasons are that the solution of temperature has been switched off, or the boundary conditions lead to a constant temperature at steady state.

By the way I think it is not possible to solve airflow with 5000 K or more with a "standard" cfd -code. Under these circumstances air is not neutral anymore.
