Hi,

I want to run simpleFoam with k-epsilon model around an airfoil. I have generated these boundaries:

U file p file
UpperCamber, fixedValue u(0 0 0) zeroGradient
LowerCamber, fixedValue u(0 0 0) zeroGradient
TrailingEdge fixedValue u(0 0 0) zeroGradient
Floww, freestream u(20 0 0) freestreamPressure
Emptyy. empty empty

Now I do not know which file I need for k-epsilon. Is it only these files : k , epsilon , nut, p and U ? what represents the files nuTilda and R , and are they necessary?

What I have done only for epsilon, nut and k files are these:

epsilon - file k - file
UpperCamber, epsilonWallFunction, u 3 epsilonWallFunction, u 1.5
LowerCamber, epsilonWallFunction, u 3 epsilonWallFunction, u 1.5
TrailingEdge epsilonWallFunction, u 3 epsilonWallFunction, u 1.5
Floww, fixedValue, u 0 fixedValue ,u 0;
Emptyy. empty empty

nut-file
UpperCamber, nutWallFunction; , u 0
LowerCamber, nutWallFunction;, u 0
TrailingEdge nutWallFunction; u 0
Floww, fixedValue; u 0
Emptyy. empty;


This doesn't work. I want only turbulence calculation around airfoil, so inlet (floww) should be without turbulence.
