Help With Honey

Postby CANCANGOR » Fri Jul 08, 2011 2:55 pm

Hey guys!

I've been working on this Honey shot for a Week now... no success.

I have a couple of Pancakes stacked on one another and Honey is supposes to pour onto the edge of the upper pancake and then start dripping(streching) down...

as long as there is an emitter sending new and fresh particles in to the stretching part everythings fine. but as soon as the emitter moves along and there are spots wich dont get any frech particles. the strechiness is gone.

The drops just break immediatly after they start streching .

So long story short. how do i get a Stretchy fluid?

My urrent settings:

Scene scale: 10
Emitter resolution: 200
Density : 1400
int: pres: 0.1
ext pres: 1
Viscosity: 130
Surface Tention 2500
MÄ°N Substeps:390
MAX Substeps: 400

dont have any deamons in the scene other than a speed deamon...

really appreciate the help

Thanks in advance!

Up the viscosity and decrease or just Zero out the surfest tension, and don't forget to increase the Substeps to get a stable SIM .

Hey
Thanks for the support !

Up the Viscosity to what? right now it is at 130 wich for me looks good. if i push it up more its not gonna look like honey anymore i think.

My Surface Tension was at 2500. . thought thats the one keeping the fluid together?? :S

anyway i have zeroed out my Surface tension and im simulating again. will let you know how it turned out.

Thanks again

Cheers!

ok i've tried to increase the Viscosity to 300 and decrease the Surface tension to Zero. the substept were the same at 390-500.

Still doesnt work. as soon as there is no emitter that gives the fluid fresh particles the whole thing just starts to break into smaller drops.

hey man. THanks for testing !

but the demo of yours seems to have the same problem as i mentioned. after a couple of seconds the liquid starts to rip into pieces(in your case the bottom balls)

Thats exactly whats happening with my fluid. Whereas Real Honey would Strechy really nice until lt becomes really thin and then rip :(

Ok i finally figured it out. I did what you suggested. No surface tension and high viscosity with high time steps.

In order to prevent the fluid from ripping into pieces. i had to use a combination of the Dragforce deamon to slow things down alittle. and most important a Sheeter deamon to close the nasty holes. Its still not exactly what i wanted to achieve in the first place. but seems like its going to do the job^^

i'll post a link when its finished.


Thanks again
