Reynolds Number- CFX Solver

As the CFX calculates I number of Reynolds? formulates it uses it conventional? according to I have understood calculates the RE node-node but the values of a calculated value theoretically and the one that is observed in solver to manager are very different 1e5 theoretical ---- 7,3e5 CFX to solver?

I must work with the theory or adjust to which leaves in solver?

The Re number reported in the solver is based on a length scale defined as the cube root of the total solution volume, and averaged velocities and material properties. This is not a useful definition of Re for comparison to literature so you must define a Re based on the length, velocity and material properties you define.
