  Hello everyone,
  
  I am working on modeling of combustion chamber of coke oven batteries.
  
  When I make the walls of my chamber insulated, the simulation works fine and gives desired results.
  
  But, when I make walls with constant heat flux, after some iterations, I got minimum pdf enthalpy exceeded and it goes on increasing the no of cells.
  
  My case -
  
  Turbulence - standard k-epsilon values
  
  Radiation Model - P1
  
  Combustion Model - Non-premixed , steady flamlets
  
  Thanks in advance
