Fluid in glass problem

Post by dennisweyel » Tue Sep 01, 2020 9:12 am

Hello,

as a Realflow noob i have a problem with a fluid

in glass simulation. The top particles of the liquid always stick to the glass and i never get a nice and even top - see picture. Does anyone know which parameter can change this? It's a SPH Fluid with 32 / 330 Min / Max Substeps

Thanks for any advice!

Hi

welcome! By the way, the first 2 posts of a new user have to be released manually.

Regarding the fluid at the glass, try to use a negative value for the parameter "stickyness" at the parameters of the glass object.

The pattern on the surface you can influence by the parameters of the meshing. Maybe use a higher value for "smoothing" and higher distance of particles to mesh, but the available parameters also depend on the mesh typ. Resolution of the fluid is also important as a factor for the final look.

Hello and thank you very much. Negative stickyness and also a little bit of friction helped. I would never have thought of negative stickyness - thanks!
