K-omega limiter
 

Hi! I'm trying to add a turbulence modeling (k-omega) to my NS code. I'm using Menter's limiter to control the production spike near stagnation point by setting pk= min(pk,20.d0*dk), where pk=production of k and dk=destruction of k.

Is there anything else i should limit? I read it somewhere that k and omega should be limited (so that they stay non-negative), but, I'm not sure what should be the floor value for the limiters or even I need them at all.
