I'm doing this tutorial.
It's very interenting, how to draw a graphic where drag cofficient depends of reynolds number.
Do I need UDF there? Or there is some other ways how to make reynolds number as a variable (From laminar to turbulent fluid).

Calculate the flow with different inlet velocities and use software like gnuplot, excel or whatever to create the chart?
