Hi,

how is it the easiest way to visualize the turbulent viscosity ratio (i.e. the turbulent viscosity over the molecular viscosity) in Paraview? To be more specific, openfoam gives me field nut, but I want to visualize nut/nu, where nu is a constant molecular viscosity.

Thanks!
Blaz

Hi,

Just use the calculator filter in ParaView. You can just provide your nu as a value there.

So your function would be nut/1.46e-5 for air for instance.

Regards,
Tom
