  • Large stepping with high viscosity values

    Not sure how to deal with this. I'm trying to simulate very thick fluid, much thicker than any of the chocolate tutorials out there, those collapse way to fast for what I'm trying to achieve. This is supposed to be more like silicone caulk. When I up the viscosity, and drop the time scale to get it to behave sorta properly, I get horrible stepping. Each step is about 2-3 cells in height. Surface tension is also set about as high as I can go because otherwise it sputters and shoots little droplets out everywhere.

    Anyone have any tips on removing that stepping, without upping the cell count even higher, it already takes forever to sim 360 frames and it splatters like crazy if I set the cell to 0.01cm. Or any hints to do real viscus fluids? I'm willing to start over as this is not working. It's supposed to roughly fill the area in with 3 passes going back and forth, and then at the end flatten out over time (animated viscosity?). And it would be nice if the fluid wouldn't combine together so fast either, if laying down 3 close layers of caulk, it wouldn't join together into a flat surface like this is doing. Not sure if that the surface tension doing that?

    Hey,

    First, your scale is really low - if you get too much splashing - up the Scene Scale in the Grid rollout more. Increasing the scale will also make the liquid appear more viscous, and you can further reinforce this by increasing the Steps Per Frame. Decrease your surface tension too - it's not a tool to fight splashing liquid, and the stepping might be because it's set too high.

    Hope this helps!
