Fluid domain issue in blender

Support Technical Support

I am wondering, why cant I use cylindrical domain instead of box domain? tried few ways by putting cylinder inside box domain but still the liquid reaches to box boundaries.
There are lots of videos on fluid simulation in blender but none of them have other than box domain used.

any views or comments on this?

cheers

I don’t know a lot about how the fluid sim is coded, but I guess boxes are easier to calculate.

You can always create a cylinder as an obstacle and trap your fluid in that…
