Fluid sim hitting invisible plane

I’m trying to use the fluid simulator to fill a glass jar. Each time I bake the simulation, the water hits an invisible surface above the jar before going in. I’ve got the render res set to 200 and it’s there too. The water was coming from an inflow. I rebuilt the scene and then added a static water source that would come in through a siphon to keep the stream look. It still hit something before the jar. I also removed the jar and it’s still hitting nothing. Any help? I’ve attached two images that show the problem.


maybe an cube on another layer?

Upload the file if you can. Someone can check your setup and maybe figure it out …

I took some things out to meet the upload size, but the problem still occurs. The water also doesn’t hit the floor. I’ve got the domain set just barely through the floor to so it should rest on the room floor.

The domain is kinda large vertically so the water can come in from off camera. I’m hoping to have a stream (garden hose style) stream in from above and overflow. Any help would be great.

I increased the fluid simulation’s resolution and it seemed to make it work a lot better. The size of the fluid’s cells might have been so large that they could not fit through the hole in the jar very well.

I also extruded the jar and used alt-s to give it some thickness. I then set the jar’s fluid volume init to both in the fluid obstacle settings. I’m not sure how much this effected the simulation (as I tried this before increasing the simulation resolution), but I’m sure a glass jar should have a little thickness anyway – as it might help it look a little more real during rendering.

Sorry to double post, but I was just thinking. Using ‘shell’ as the jar’s volume setting may possibly add a boundary space around the surface of the mesh. Using ‘volume’ as the volume init would, I assume, use only the space inside the volume of the mesh as the boundary. Of course, the glass of the jar would still need to have a little bit of thickness. Having the volume init set to ‘volume’ may be the best choice if used with thicker glass and a higher resolution simulation.

That makes sense about the boundary box which is about where the water hits first. I think I might just make the jar bigger rather than make the water particles smaller and then make the jar a volume with a surface defined inside. thanks a lot for the help!
