Hi!
I would like to assess the head losses in a pipe with two elbows.
I fixed the pressure P=0 Pa at the end of it and, also, I put a flow rate as boundary condition in the inlet.
When i am going to check the pressure at the beginning of the pipe, this is less than zero, which it is impossible since the head losses have to be positive.
Could someone help me ?
My project is the following:
Simulation: TAILRACE. RUN 1
Thanks for all,
Cheers.
