jyothishkumar is on a distinguished road
Hi all,

I have written a NS code for 2d pipe flow with std kepsilon (high re no). Now i am trying to implement the low reynolds number model in to my code. Now my yplus value also reduced to very low value (<5). Also i am implementing the damping function fmeu, f1 and f2 (Lam and Bremhorst model with k=de/dn = 0 at the wall). But after around 640 iterations my solver is blowing and especially it is due to f1 and f2 value. Is there anything that i missing out here. Can anyone help me in this regard.

thanks
