Hi everyone,

I am new to OpenFOAM and would like to model turbulent flow around a cylinder. I am using pisoFoam with k-e model.

For the epsilon boundary condition, I am using "epsilonWallFunction". in the description of this function in the user guide, this syntax is available

// Mandatory entries (unmodifiable)
type epsilonWallFunction;

// Optional entries (unmodifiable)
lowReCorrection false;
blending stepwise;
n 2.0;

// Optional (inherited) entries

when I am running the pisoFoam, it is asking for a value for this boundary condition. Also, in the tutorials, I see that a fixed uniform value is given. This means that epsilon should have prescribed value on the walls?

Thank you for any help.
