Hello,

I calculated branced pipe flow. I used k-epsilon model because I wanna initialize the model for LES. I injected water and apply pipe wall friction. Gravity is not considered. I have some qeustions.

1, continuity and epsilon does not converge and cannot be lower than 1e-6. I think it is because of the mesh, could you give me some advice what mesh should I apply? 

 

2, I found bumps on the wall when I see velocity pathline, is this due to wall friction?

Please review the training materials in Learning re convergence. 

Looking at the above, please plot a velocity contour on the centre line plane with node values off and post the results here.
