Really thought i posted this earlier... guess i did not. I'd love to pick you guys brains over how to go about simulating viscous fluid with absolutely zero friction... mercury style or so. I've turned off all friction on my particles the viscosity and surface tension aren't over the top and yet the fluid just sticks to the collision objects. Any pointers more than welcome.

Cheers,

Hi, no example but an idea. There is a video by indie-pixel [www.youtube.com] that shows how to use volume gradients with height fields. Something like that could be used for a collision/velocity field to imitate an oily surface. I guess there is no default option to handle this as viscosity is just a velocity/pressure damping (not sure).

Hi, you can create slip field around your collider, and bring then into dop and use use it on flipsolver,
there is tab on viscosity use slip field

Not directly related but very intersting watch, some very useful vex snippets in there i had actually never used, loved it. thanks.

thanks, i had missed that, my first with non-sticky viscous flips, glad to see this was addressed and ready for use. Much appreciated. Thank you.
