k-e initialization
 
Hi,

I have this highly turbulent flow inside the pipe with too many details inside.

I have difficulty getting convergence and I am trying to improve my initial guess for k and e (I am using k-e RNG turbulence model).

I want to use high initial guess for k and e to stabilize my flow. should I only increase my e or k also should be increased at the same rate to get better convergence?

thx
