Density for calculating Force Coefficients
I am plotting force and moment coefficients on an aerofoil in a transient simulation, as user points in CFXsolve. Currently these are based on expressions I have inputted into CFXpre, eg
Fx=force_x()@aerofoil=> gives the force on the surface CFx=Fx/(0.5*Rho*U*S) => gives the force coefficient With these I specify the density value for Rho beforehand in CFXPre. However, is there any way I can assign the value for Rho as the flow density say over the inlet boundary, rather than as a value I specify? Thanks in advance

Hi,
I'm not sure this is what you want, but you can create an expression for Rho: Rho = areaAve(Density)@inlet.

Thanks Rui, thats just what I'm after
