Greetings,

I have question about displaying images in paraFoam.

In paraFoam (case twoPhaseEulerFoam), after loading time
data, there is a "Display" tab which have further choice
of "Color by". There are many choices corresponding to
variables to be displayed.

There are
void Pointinterpolate(nutb)
void Pointinterpolate(U) (3)
void Pointinterpolate(Ur) (3)

in addition to variables from 0 directory.

I do not have those 3 variables liste in 0 directory.
What do they mean and are they for?

niklas will become famous soon enough
Those variables are calculated by the code and you dont need to specify them in the 0-dir and I suggest you take a look at the source to find out what the variables are.

nutb - turbulent kinematic viscosity of phase b.
U = alpha*Ua + beta*Ub
Ur - relative velocity of phase a and b
