Hello
have still little problem with meshing particles in houdini. im trying to do something like caramel but have problem with viscose liquid. Look at the vimeo. First problem is with particles. Viscosity is 1500 density 1000. If you look at the caramel on top of the bending edge, particles there does not stick together and jumping to next surface.

Second problem is with meshing, standart settings Average position. Problem is with big curvature and ofcourse particles which jumping to the next surface. But I have still problem with this strange meshing thing in another different scene. Mesh is creating where is no particles. Any idea? This is just test scene low res. Thanks a lot.

There's some tips for working with viscosity here:

In particular, the Average Position surfacing method often leads to the artifacts you're seeing. They're less noticeable with fast moving water, but for slow, viscous fluids I usually use the Metaball method.

You probably also want to turn off reseeding, which tends to fill in the gaps between parts of the fluid surface.

Thanks a lot Johner,Ill try it.
