Hello everyone!
I want to use non-dimensional form Navier-Stokes equation in my 2D spf laminar flow simulation.
The equation in non-dimensional form (using Reynolds number, Re) is attached in the figure. Please some one help me which setting in COMSOL 4.2 I have to change so that it uses one of the non-dimensional form of equation as in the attached figure.

Thanks in advance
Siva

May I request Dr. Ivar to help me?

Dr. Ivar, would you please tell me how will I convert NS equations into non-dimensional as in the attached figure? Please help me....
thanks
