Simulation of tiltable bucket with water
Hi!
At first, sorry for my terrible english ;-). I am trying to simulate a tiltable bucket with water. I am working with CFX-Ansys. I made a PDF with pictures of my settings from this simulation in CFX. And I uploaded a video with solution of this simulation. I am not realy happy with solution of what a have. If you look at my video, you will see domain “water” peel off. My question is, what i did wrong? why does water domain peel off? Thank you.

Sorry, I do not have tiem to view your videos but I saw the PDF. Your mesh is very coarse around the bucket and this will cause massize smearing of the air/water interface. Simply putting a finer mesh will improve this a lot.

I made a little bid other settings on interface between water and air dyn. I changed the "pitch change" option from automatic to none and it works)))) Thank you! |
