Convergence in Fire Sim
 

hey,

I am simulating fire in a compartment as heat source and smoke generation as mass source with species transportation without reaction. I am not able to achieve convergence at all. The problem can be taken as natural heat convection with species transportation without react. So any suggestions about setting the solution control (solver, pres-vel coupling, discretization, URFs...). Any reply would be really valuable and thanks in advance kam
