Turbulence error
 
Hello CFD member,

I am using LRT k-omega for my work: 2 phase flow.
But when I ran, the kinetic energy and omega had negative value. I dont know what and why got that error.
Anyone can help me?

What solver do you use? In OpenFoam I get these kind of errors, when there isn't enough dissipation in my discretization schemes for k and omega. Such as when you use linear interpolation. Try first order / upwind for the convection of k and omega.
