RHS - Right Hand Side, ie the bit on the right of the = sign. nFor the above you're after the velocity at height z (I think). That would be an input from UDF or expression. Assuming the line is on the inlet you can just report the velocity. If you want to calculate to compare to the input you'll need to code in the equation:n ( ustar / kappa) * ln(z / z0) At a guess, ustar and kappa are constants, as is z0 (usually ground level) and z will be the coordinate under mesh. n
