Hi,
I need to simulate the emptying of an object through a hole in the floor, after a plug is pulled.
Is there a way to use an object which is already filled with liquid? Or do I have to fill it first?
Thanks in advance
Yup, depending on how your scene is setup, you can either fill your simulator to some level using the Liquids->Initial Fill Up option (it’s 50% by default), or if you need to fill something with a more complex shape, you can use the PHXLiquid in Brush mode, and animate the discharge to 100% for a single frame and then back to 0 - this way you will imprint the geometry shape into the simulator in the form of liquid, you only have to exclude the emitter geometry from interacting with the simulator - with the official version 2.1.1 this happens from the Interaction rollout, or with a recent nightly build you can do it form the phoenix right-click menu of the geometry.
In either case you may need to wait several frames for the liquid to settle.
Thank you!
I was still using 2.0… now it makes sense.
Since I have to empty an object, I’ll try the PHX-Liquid-Method.
Or is it possible to fill an object with the Initial Fill Up option?
Once again: Thanks a lot! I’ll try different things now…
Or is it possible to fill an object with the Initial Fill Up option?
unfortunately no, the initial fill up option fills the grid, not an object
Thank you!
Last question: The “animate the discharge to 100% for a single frame and then back to 0” did the trick. But the discharged water doesn’t interact with other objects. Nor with planes, nor with sliced geometry. So I cannot “fill” a box, because the liquid falls through the geometry…
use boxes instead planes, they are too thin. the liquid simulations need at least two cells thick objects
