eetu Here's another variation, melting by transfering low viscosity by a metaball. To determine the centipoise of a fluid it is necessary to multiply the viscosity. Unfortunately the viscosity solve is fairly expensive, so increasing minsubsteps can be painful but necessary sometimes. Increase Minimum Substeps until you get sufficient viscosity. A slow moving, highly viscous sim might need more substeps than the 1 that the FLIP Solver will give it based on its velocity. While the viscosity solver should always be stable, it will be more accurate with smaller substeps. Blended flower honey has a viscosity of about 12,200 cP at the same temperature, according to more research. Water and oils are examples of Newtonian liquids. With other fluids such as oil, varnish, yoghurt or honey it can significantly. The viscosity value decreased with the increase of temperature. Viscosity is typically measured in Centipoise (cP) or Centistokes (cSt). This issue can crop up as well with high viscosity values: The FLIP Solver computes the number of substeps to calculate based on velocity. Honey’s viscosity at a room temperature of 21.1☌ is 10,000 cP, according to a quick internet search. 1 Centipoise 1 mPa s (Millipascal Second) 1 Poise 0.1 Pa s (Pascal Second) Centipoise Centistoke x Density Newtonian materials are referred to as true liquids since their viscosity or consistency is not affected by shear such as agitation or pumping at a constant temperature. Influence of temperature on the viscosity of honeys was analysed in the present work. Some of the things that work well for inviscid fluids, like reseeding and automatic detection of ballistic particles, can be less useful or even counter-productive with highly viscous fluids.
The section on viscosity in the docs has some info that might help keeping the viscous fluid together. On the other hand, fluids that take time to flow, like honey and glycerol, have high viscosities. Circusmonkey As the surface falls FLIP does struggle to hold itself together. Fluid Viscosity Chart Pourable Urethane Rubbers, 1,000 - 3,000, centipoise (cps) Honey or Corn Syrup, 2,000 - 3,000, centipoise (cps) Molasses, 5,000 -. Water has a low viscosity since water can flow readily.
