Hello,
I would like to have contours. and So, I create the variable uplus like this: HTML Code:
// Wall Shear Stress wss = sqrt ( Wall Shear X * Wall Shear X + Wall Shear Y * Wall Shear Y + Wall Shear Z * Wall Shear Z ) uplus = Velocity / sqrt ( wss / rho) But then I realized it should be 0, because Velocity is 0 at the wall. So I tried something: 1- If I plot the velocity at a wall 'directly', I have 0 everywhere, it's ok (face values) 2- If I create a variable equal to the Velocity and plot it at the wall, I don't have 0. So I think that when you create a variable, it's for cell centres, right? It would be nice since it directly take the first cell from the wall to calculate
