How Can I Apply Convective Boundary Conditions?
 

Hi -- I want to apply convective boundary conditions at an outflow. Mathematically, this is what I mean:

partial{u_i}/partial{t} + U_c.*partial{u_i}/partial{x_i} = 0

... for each component of velocity {i}. (Where U_c is known/specified)

How can I do this in Fluent?

Thanks
