boundary condition for outlet

Please login with a confirmed email address before reporting spam

i have a small doubt regarding the otlet condition in fluid flow simulation.
if i have a outlet tangential velocity is not zero, can i use outlet condition directly,
or do i need to create a imaginary long section at the outlet where the flow can be assumed to be normal and then use the outlet condition,
