A question about epsilonWallFunction

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 <patchName> { // 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. |
