FLIP stability

[flipbook]

Hello again

I ran a detailed sim, I think it was about 61 million cells and about 19 million core particles. Anyway I am using initial fill up and open boundaries. You can see a constant wobble in the liquid/secondaries. Is it best to leave the container to settle down before main simulation or is it best to have closed boundaries?

Not a major isssue as I am just testing but would like to know peoples thoughts.

this is a known issue, but in your sim it's very strongly pronounced. the closed boundaries are not good idea, they reflect waves, and the most important the front wave is very different, the water has no place to step back.

Ok, as long as it is a known issue that is fine. I have used open boundaries in that shot. Shall experiment to try calm it down a little bit more.

Thanks
