Byter3 Posted October 25 Share Posted October 25 Why surface tension utterly useless in Flip? What's the issue: Fliptank initial, using narrowband. If surface tension enabled, the entire surface is full with artifacts. It actually looks it raining onto the surface. Does anyone have a solution for this? What I already tried; Playing with the substeps playing with the grid scale playing with the jitter scale on the fliptank source Tried with and without opencl Here are two tests, one with surface tension enabled and one without it. https://drive.google.com/file/d/1W3sYyYcXctdzkAvncXZqQRDl2tDAjtLY/view?usp=sharing https://drive.google.com/file/d/1msCtg_OXd7_ej0EyjDYm078Lri1JIJQL/view?usp=sharing Quote Link to comment Share on other sites More sharing options...

haggi Posted October 26 Share Posted October 26 And, yes, large scale flips do not work very good with surface tension, following the docs, it is mostly useful for small scale flip sims. Quote Link to comment Share on other sites More sharing options...

Hey, updated the link, you should be able to view it now. Also, this supposed to be a crownsplash. It started from the shelftool. Quote Link to comment Share on other sites More sharing options...
haggi Posted October 26 Share Posted October 26 Not sure what you changed, but this is my splash after increasing the gravity to 0,98 and increasing the surface tension to 5. Looks pretty stable to me. splash.mp4 Quote Link to comment Share on other sites More sharing options...
Byter3 Posted October 26 Author Share Posted October 26 You can se the same thing at the begining and when the impact wave propageates. Set you surface tension higher it will be more visible. Quote Link to comment Share on other sites More sharing options...
Byter3 Posted October 26 Author Share Posted October 26 (edited) brand new hou scene, using shelftool for crown splash, the only thing I changed is cranked up the surface tension to 25: Espically visible, when I try to decrease the density of the fluid.

haggi Posted October 27 Share Posted October 27 The color of the particles does not say too much since in the default scene it is set to range 0-1 if I remember correctly what is really, really and captures the smallest movements. So the final mesh is the the more interesting result I think. Quote Link to comment Share on other sites More sharing options...
