divergency of combustion calcualtion
 
The question is : when the simulation of combustion is calculated, because there are several outlets . convergence is very difficult.who can give me some hint.

Thanks. The furnace has several outlet in difference position. The outlet mass flux can be know. The fuel is air. when the calculation is doing, the warning messages have two type as following: 1, *** WARNING #007 *** SETTING T AT CELL 18157 FROM -4.076E+00 TO 0.01*TREF FOR DENSITY CALCULATION

2. *** WARNING #066 *** TEMPERATURE LESS THAN MIN. RANGE TEMPERATURE AT 1 CELLS.

MINIMUM TEMPERATURE OF -.120E+04 AT CELL 19262

what is best method to debug it.
