Boundary Conditions
 

I´m doing an example of the cfx Tutorial ( Can Combustor Chamber) and when they are triying to especify the cartesian velocity components in the boundary conditions, they used a ecuation ( U=400*y), Where that "400" came from?.

Someone can help me?

Take care!!

That is just an example. You can have your components of velocity in function os position(or anything you want), e.g. U=f(x,y,z) ; V=V(x,y,z) and W=W(x,y,z), instead of a constant value, the reason why the subroutine was developed.
