Phoenix FD and Chocolate simulation

[Blakk77]

Hey there, I'm kinda new user for Phoenix FD and suddenly I came before the task to create pouring chocolate over some candy bar
so chocolate would kinds pour and stick over the surface.
So any help and ticks would be appreciated....

you can use the scene visc.max (my documents\phoenix fd\samples) as a starting point.

thanx a lot, just one more question, why temperature is used in liquids instead of fuel?

[Blakk77]

now...fine example
but one thing
everything works just fine as long as scene is static, as soon as I animate source object it starts to get ugly with particles flying all over scene and not only in desired direction

[Ivaylo Katev]

the temperature is using because the liquid simulations are derived from cold gases simulation.

[Blakk77]

thanx, and is there a way to avoid strange atrefacts and particles flying around while animating a source?

Here`s simulation with static source


and here I did some simple movement of source cylinder with same simulation.....

[Ivaylo Katev]

very probably this is a bug, it seems like the velocity of the released fluid is bigger than the correct one, you can fix this enabling the velocity checkbox in the source and decreasing the multiplier, or directly zeroing it.

you can also try to use non solid source in brush mode, or to lock the simulation container to the source.

as I found out it is more advection method fault than velocity, changing to smooth solved the problem. but result it s not like i wanted to...
and how to do non solid source of lock simulation?

[Ivaylo Katev]

non solid source is a source that uses a geometry disabled for interaction with the simulation, i.e. hidden object or object added to the disable list. to lock the container to the source means just to make the simulator a child node of the source
