hi if you look at the video (many slide the timer slowly) you will see perfectly smooth water and then water gets very noisy like there is a turbulence but there is no turbulence. How do i get rid of noisy looking water. I know robot is mooving in the water by why noise is through out the whole room. We are using fill box and for some reason water never settles to 100% still and smooth. Thanks
noise .zip (5.12 MB)
are you using vray sun? it could be the specular from it that causes the noise.
Yeah that looks weird I’m not sure what it is 
any vector displacement on the fluid?
Hey,
It’s not really that mush velocity - in the channel range you can see it goes from 0 to 5, where 5 is voxels per second - the preview automatically adjust because of the Auto Range, so it can show you reach data.
Give a latest nightly a shot - there were several changes involving border conditions, so the higher velocities on the simulator walls might go away.
However, I know of an effect where if you leave static FLIP liquid long enough, it would start creating some patterns which I think I know how to suppress, but with a latest nightly there should be at least some improvement.
Another thing I’d suggest would be to try and raise the grid resolution - 1.5M is quite low right now and boosting it to 10-20M will change the behavior, hopefully in a better way.
Hope this helps, cheers!
