Hi,
I simulated a case of a floating body in shallow water which unfortunately I cannot share. It compares very well to experimental results and everything seems good, until I look at the turbulence modeling (komegaSST RANS model).
I want to visualize for the eddy viscosity ratio, For water I used nu=1e-6. m^2/s, Vorticity looks like what i expected but nut gives values of up to 0.001m^2/s.

Using the paraview calculator and just dividing nut/nu for the water phase gives very high eddy viscosity ratios...
I cannot find the error and the dimensions seem correct, is it still possible that I need to divide by density? Is there a bug in interFOAM in OF 2.1.x?
Dividing by density of water gives much more reasonable results but I cannot justify it...

Confused....
Cheers,
Pal
