Help obi fluid vibrate problem

[josemendez]

I tried both but not working. the glass has "rolling friction" collision material, I changed it to low friction, and it is fixed.

thanks for note   

Why would you enable rolling friction on a fluid simulation? that's usually only useful for granulars. Unless you're using granulars in your simulation too, imho you should disable it.

then I rotate object has box collider, the jitter is disappeared.

Not too sure why would rotating the collider would fix this, though. I'm not sure I understand your setup. If problems persist, could you send the project to support(at)virtualmethodstudio.com so that I can take a look at it?

thanks!
