Liquid pours out strangely

Hi this little toy excavator scoops up the water but it pours out so strangely. Am i doing something wrong. Thanks

Hi,

it really depends how the excavator is animated. If the animation contains parent and children (static origin (joint) and geometry transforming around it) it ain't gonna work. It's a known problem we're working on it. The solution here would be simple animation in which the whole thing moves like it's one geo. Just for a test, you can detach the bucket and animate it through Z-axis. Also, remove any additional geometry in the bucket (because if there's an open geometry could cause a strange behavior).

thank you for explaining . yes excavator bucket is a child.

HI We have the scene where door opens and water gushes out of the kitchen. It starts ok first 3 seconds but then water just slowly drains almost like it has no water pressure. One side of the grid is unjammed and that is where water escapes. Anyway to add more pressure to the water to see more force especially near the door. Thanks

Have you tried using a source with a negative value?

Hi,

A source with negative discharge alone will help consume the liquid faster, but will not help distribute the pressure. However you can combine it with a body force to attract the liquid to the negative source.
In most VFX oriented simulators the pressure effect decreases rapidly with the distance, so the best thing to do in this case is to use force helpers. I would suggest using a follow path force with big pipe radius, rotation speed set to zero, very low pull speed and a bit higher follow speed.
You can also experiment with one or a few weak plain forces to create a flow in some general direction.

Thank you all. It seems that plain force set by the doorway helped. Hopefully a real water pressure will be possible one day
