NOT Mass converges on Turbulent Diffusion Flame -- CFD Online Discussion Forums

Yoon Guest Posts: n/a	Hello. I'm developing my code for turbulent diffusion flame based on SIMPLE Algorithm. It uses the set of equations in FLUENT and consist of the staggered grids. (K-Epsilon turbulence model,Presumed PDF Model) : Primitive variables are Dynamic pressure, u, v, mean mixture fraction, and mixture fraction variation. In cold flow simulation, it operates well, but with reactions, the mass is not converged. Have you experienced this problem? I'm so exhausted to solve this problem.
