I'm looking into SPH for some water runoff stuff right now, but for the life of me I can't figure out how to make it cling to collision surfaces. I thought that some combination of viscosity and surface tension would give me the cling but I haven't been able to even approach it, the particles just roll off like racquetballs. Basically what I'm after is this; http://www.realflow.com/html/training/tutorials/Particle_interaction_Particles_Vs_Objects/Sticky/sticky.html [realflow.com]

The levelset fluids have a sticky option but the resolution required for sheeting water is prohibitive. I would be more than happy working with crept/clinging particles in pops if there were some way to integrate SPH forces there, or likewise using cling through a popsolver in dops, but i haven't been able to get SPH and the popsolver to play nice together.

Have I missed something on the PF Object/Solver, has anyone tried something similar?

This has been brought up before - it seems to still be an outstanding problem.

Maybe submitting an RFE?

Yesssss, that's what i was after. Tanks!
