Hello
I want to read velocity profile from outlet of a pipe and impliment it as BC at inlet to another pipe.
I can do that but I am strucked to very basics.
What velocity components should I copy...I mean Velocity Magnitude or Axial Velocity etc.??
Hope to get a reply soon.

if the pipe is axial symmetric, copy the axial and the radial velocity.

Otherwise, you copy the components in x, y and z direction.

And select for velocity inlet "components and direction"

Additionally, if your flow is turbulent and if it has temperature changes, you have to copy the turbulent and temperature quantities as well.
