Hello,
I don't really understand the difference between the boundary conditions put at the outlet between 'inletOutlet' and 'zeroGradient'. I could not really find a website where they really explain the physical difference between the two (no clear explication is given apart from two descriptive lines). Could someone please explain to me what these two conditions mean? Bonus question: what would you recommend putting in a tube where water flows in and out in a sinusoidal fashion (water enters and comes back sinusoidally)? Thank you! |
