I'm trying to make a fluid-water simulation, where the ball (effector) comes from underneath the water, penetrates through the water and makes a major splash. But once the effector comes through the water, the water simulation starts rising within in the Domain cube. I want it to remain in its initial position. which settings do I need to tweak?

  • $\begingroup$ it's pretty weird. I can only assume it is a bug. Did u try filing a bug report? $\endgroup$

  • $\begingroup$ or maybe it is "just" a rounding problem. I just raised the resolution to 64 and i got [1]: i.sstatic.net/Rfv2L.png -> so maybe "just" a high resolution will solve your problem $\endgroup$

Your Initial Velocity for Source on the "Fluid Liquid" mesh was set at 1. Changing it to 0 stopped the water from rising.

This is what yours was set at:

This is what I changed it to:

  • $\begingroup$ if this really solves the problem, i would report it as a bug because initial velocity wasn't checked and shouldn't influence anything (and with "geometry" there should no velocity at all). I just tried it out and my result with Blender 3.4 looked like this: [1]: i.sstatic.net/5WV6X.png ...so even worse. Maybe it is better on another Blender version. I didn't try that. $\endgroup$

  • $\begingroup$ I tried putting the velocity to 0, and also removing the Effector, but the fluid level still rises above its initial position: ibb.co/M7HWPB5 $\endgroup$

  • $\begingroup$ A good example, is this video footage here, the surface explodes, but the level remains as it is, the sea water doesnt rise: youtube.com/watch?v=ydWLkyMRfaU $\endgroup$

    $\begingroup$ I added a bug report for 3.3.1, Once the object is set to effector>Guide. When I try to add keyframes in the timeline, Blender crashes. $\endgroup$

    $\begingroup$ developer from Blender, is working on the bug, I was emailed today. I don't know if this will help my current issue with the liquid rising though. developer.blender.org/T102257 I also posted a video of the problem in Blender artists blenderartists.org/uploads/default/original/4X/5/9/0/… $\endgroup$
