Gravity in a water pipe cfd simulation


I have a problem when I try to consider the elevation in a pipe section network in the following project, simulation “TAILRACE”:

How can I take into account the gravity or the elevation difference betwwen the inlet and outlet surfaces?

Thanks for all!

Hi @andrea_perez!

You can find the answer to your question here: Setting gravity for incompressible flow - let me know if that helps!

Well, if i don’t change my type of problem from incomprensible flow to multiphase, how can i know that my model takes into account the elevation on Z ?

Thanks for all,


Don’t worry, the solver will take into account all the change in elevation.
