Make liquid stick to fast moving objects

[tim_smit]

Hi Everyone,

Perhaps any of you could help me out with this problem. We have a liquid simulation that needs to stick to the fast moving ball (see reference video). The current setup uses:

6 substeps
Stick liquid: 1.0 (max)
Liquid friction ball: 1.0 (max)
Particletuner is used to increase the liquid's viscocity just around the ball to 50+.

What else can I do to ensure the liquid stays sticky once the object starts to move?

All the best,

Tim

Just to be sure have you added wetmap? otherwise sticky liquid won´t work

Ah, this one would be hard to achieve. If the ball was alone in this setup, I would have recommended to parent the grid to it, so when moving, the liquid would be calculated more precisely in relation to the moving geometry. However, there is also the ground geometry.

Something that might work out could be to indeed use one simulator parented to the ball, and another static one for the ground, with cascade connection from the moving simulator to the static one, so the liquid would move between the two. However, note that a cascade connection would only allow for liquid to move from the static one to the moving one, and not the other way around, so this might also be limiting...

Hi, thanks for your response. I'll see if the moving simulator ideas works, pretty clever. It would be great to have the option to really 'stick' something to an object like this!

Ah, btw, one more thing that I thought of - if the liquid over the ball is going to be just a thin layer that would not do have to do any liquid stuff after it flies off, you might try something else - to mesh the wetmap particles and apply the same material to them as the other liquid mesh. This way you would have two meshes intersecting for a part of the simulation, but since the material is not translucent, it should not be visible. Here is a video of how to mesh particle systems other than the liquid - you just need to pick the wetmap particles in the particle texture: https://youtu.be/6J5XjLeZQyo
