RNG ke - natural convection
 
Dear all,
I am using RNG k-epsilon model for natural convection. I increase the gravitational acceleration (g) gradually. Until g = -4 m/s2, by changing under-relaxation factors it converges. But, although I am using the same procedure as the previous gs, it does not converge at g = -4 m/s2.
I would appreciate if anyone could give me advice.
Thank you.
