Natural Convection Inside Square Cavity
 
I am doing analysis on natural convection inside square cavity 2 dimensional by taking adiabatic top wall, two vertical walls are cool and hot bottom wall and by varying rayliegh number 10^3 to 10^5 i have to get plot of stream function and temperature profile For this I have to normalize the velocity, temperature, and length and i have to give input as dimensionless velocity,temperature,length in STAR CCM+.But tutorial given in STAR CCM+ is not usefull much. I need help for following question...

1.How to normalize Velocity,temperature,and length to in the range of 0 to 1 ?
2.How to give input as dimensionless value in STAR CCM+ ?
3.Actually I cannot give the direct input as rayleigh number in star ccm+ , by varying which function i can get the effect for desired rayleigh number..?

:(:confused:
