My search ninja skills are crappo and couldn't find the info. Is there a surface tension attribute for Flip?
Thx!

Hi,
Surface tension is handled as a field, so there is no particle-based attribute. It essentially computes the curvature of the fluid surface at each voxel and scales that value by the global surface tension coefficient in the FLIP solver.
It's possible to achieve variable surface tension by creating your own attribute, stamping it to a new field (using Gas Particle to Field) and scaling the surfacepressure field by this new field.
Hope this helps!

thanks Ryan! I'm getting wacky results currently and want to work it out myself. Getting the attribute from Sops to Dops is proving more troublesome than I thought!
I'm looking at using the viscosity attribute as an example and can't see it in the Geometry Spreadsheet attributes in Dops anywhere. I sillyly thought the attribute would naturally import into Dops but I see that the visocity is brought in in /obj/AutoDopNetwork/flipfluidobject1/particlefluidobject/particlefluidconfigureobject/convert_to_particles
Do I need to replicate that setup for the custom Surface Tension attribute?
Thanks!
