Emerging from fluid

Are there any plans to set physical properties like wetting for certain meshes (not global)?

It's a good idea and I will add it as a feature request in our system.

Awesome

the per object wetting was discussed one year ago when this video was created. it will be added, i hope for the official release of 2.2

Glad to hear that

Hey,

I have a similar issue. (I'm still using Phoenix FD 2.1.1)

I use one polygon of a simple box as emitter.
Its height is animated up and down (z-axis) over 50 frames.
The discharge starts at frame 0 with a value of 6. From frame 25, the discharge is reduced and stops completely at frame 50.

So far, so good.
However, at each collision with the grid walls the amount of liquid appears to continuously increase.

What could be the cause of this phenomenon?

Hello! Volume problems are usually fixed by changing the advection method. Generally the Classic advection tends to gain volume, while forward transfer tends to lose. Multi-pass is closer to the classic method, but you may try it out too to see if it helps your scenario.

this phenomenon is caused by the classic advection, it requires high spf value to observe the conservation of the liquid amount.
you can increase the spf or to use ft if you have nightly access. for the official build only the first option is valid, because as svetlin said, the ft loses volume in the official buid. this was fixed about month ago, so you can use ft only with nightly build

Alright. I increased the spf to 4. That already helped. Will continue tweaking...
Thank you!
