I am trying to simulate fluid flowing in the top and out the bottom of a tank through pipes. A little like in this picture:
At the moment, the top inflow seems obstructed for the first few frames and then flows in an unrealistic, obstructed way. Please see the gif:
If you look at the top pipe, it is not flowing smoothly. I've tried rotating the inflow object in the top pipe (90 degrees), checking the surface normals are all pointed outwards and giving the inflow a slight positive Z initial velocity and none of these seemed to make a difference.
It might be worth noting that when I run the animation without baking the mesh I see just a small amount of fluid flow along the bottom of that top pipe.
I am new to this so forgive my ignorance!
I think I read somewhere in the manual that if you have multiple fluids in your scene you're supposed to design them separately and then combine them later? But I didn't understand it really and now I can't find that part of the manual!
