hi, In fluent I need to apply convective boundary condition at outlet.
It will be very helpful if anyone can do this udf.
d(phi)/dt + u*d(phi)/dx = 0
((phi)i,n-(Phi)i,n-1)/dt + u*((phi)i,n-(phi)i-1,n)/dx = 0
i= space index, n= time index, u= outlet boundary normal velocity, dx= space step, dt= time step
