The streamlines are the velocity field. If you ignore that - then why bother doing CFD?

Yeah I want to define Re Number as an expression in CFX-pre, and then drag coefficient. In that way I can define a new drag model than a common Schiller-Naumann correlation. Thank's a lot. Regards, Sep |

Have you done the tutorials? They show you have to implement CEL expressions.

In CFX-pre in the tree to the left you have stuff like Simulation, Analysis Type, Solver, Coordinate Frames, and a thing called Materials. Right click, insert/material. Or from the menu in the top, click insert/material.
This is the easy part with CFD, and if you have problems with this you should at least do all the tutorials before doing anything else. |

First of all, Fluent is a dimensional solver so you need to change the velocity, size or fluid properties to give the Reynolds number you want.
Secondly, this is the CFX forum. For questions on Fluent try the Fluent forum.
