Default Additional Variable (Non-Dimensional) in CFX-pre

Hi,

I wanna make everything(all variables) non-dimensional in CFX-Pre. I think to do this, I have to make additional variables(non-dimensional) for Momentum and Energy Equation.

Can anybody help me to do so?

I have made the airfoil coordinates non-dimensional with respect to the chord length. So, now for flow analysis, I need to make other variables non-dimensional.

Actually, what you need to do is make the airfoil coordinates dimensional. Scale the geometry appropriately. You can then pick your fluid properties and boundary conditions to match the appropriate non-dimensional parameters (such as Reynolds number, etc.).
