Non Dimensional Simulation
 

Dear All

I like to know if it is possible to do non-dimensional simulation with CFX; because I like doing my simulation with different Reynolds number.

Yes, you just need to transform the input variables into non-dimensional ones. For instance to model flow over a cylinder at Re=100 you could draw the diameter at 1m, use a 1m/s inlet, and set the density to 1kg/m^3 and the viscosity to 0.01Pa.s.
