Fluid inside a Can

I have a fluid object (cylinder) inside a glass tank but and set to fluid and volume to but as you can see the bake process had chopped off a section

any idea why this is happening

You need a very, very high resolution simulation in order to fill an object. You may be better off using SPH particles, but there’s currently no good way to surface particles in Blender.

it was the resolution that caused the chopping, increased resolution fixed the issue

obviously this thread has been resolved, Admin please close
