Collisions extremely imprecise for concave objects #8
Comments
Try to recalculate normals and make thicker walls. |
But BTW it will be nice to have more control on the collison objects. |
Btw: I also tried adaptive time stepping. |
I just did a test - SPH fluid particles also can handle the obstacle. I wonder why FLIP cannot when both the particle based and grid based simulations in Blender manage so? |
The reason it's currently failing is in fact because of the "thin" walls. |
Being able to have simulations with thin obstacle geometry would indeed be awesome 👍 |
Hi everyone, yeah, maybe we could add some options to "thicken" the surface. It should be possible to relativley easily fix this with the tools mantaflow already has... But it's a good point - we'll need to be able to deal with thin obstacles.
Cheers,

Yeah currently still a bit of dripping is occuring. |
You mean with the mantacup.blend example? I found surface thickening and adaptive time stepping fix the issue in that case. Can you post a screenshot with settings? |
I tried a new example: https://www.dropbox.com/s/wwy5ik1aaow6i1n/cup.coffee.classy.blend?dl=1 To test, set the domain size to 128. It's only a few droplets that get away... |
Increasing the thickness value of the cup seems to help in this case. Note that the value doesn't scale with grid size though (not ideal but good for now) |
I created a really simple cup to fill it with Mantaflow liquid. Yet even at resolution of 128 it is impossible:
