hi
i try a simulation of two different fluid, the first flow in a tube, the second outlet of this. so i have two inlet faces and two outlet faces. when i open inizialite i should choose a condition to start simulation. which is it? there is a method for use both inlet condition?

the initialization will affect value to each solved variable FOR THE WHOLE DOMAIN.
For instance an initialization with velocity 1m/s, means all the cells will have 1m/s as first guess solution (except BC of course)
Now if you want to separate your domain with different initialization, you have to create domain, and patch the domains with desired initial values

thank you MAX
there is a tutorial where show it (use of patch) ?
