Hi, i need some help with this.
The first problem is with the kill daemons. I've just tried to use 2 kill daemons in the scene, one not animated, adjusted to the domain, but a bit smaller, so that way the particles doesn't collide with it, and the other animated following the emitter and killing the particles behind it. The image is just a basic representation of my scene. And it always crash after some frames and i can't finish the whole lenght of the shot. I've read there is a bug with the kill daemons, but anyone knows how can i solve it?

The second one is at some point, in my simulation appears like towers of water but there is nothing there to clollide with. You can see on the picture "Towers of water". How can i solve it? I've increased the min substeps value, and put some jitter in the emitter, but it still appears.

The last thing is about the distribution of the IDOCs. If you look at the picture "Scene_distribution", you see there are 5 IDOCs alongside the domain. It is because i only have 5 nodes and i just one send only one IDOC per node. But i think it is ok because they are working during the whole shot, because the wave is moving alongside the shore. What do you think? Should i distribute it in a different way?

Thanks in advance.

Hi Victor,

I believe you are trying to distribute the base of the simulation, and that is not possible.
The IDOCs are there to help distributing parts of the scene that don´t need to interact with each other.
When using Hybrido, IDOCs are normally used to distribute in the farm the generation of secondary elements such as splash, foam, etc. that use a pre-cached grid simulation.

I hope that clarifies.

Best regards,

wow. Ok, i understand, so is there anyway to use the render node with the basic fluid simulation? For example, can i simulate different frame ranges with a bit overlap with different IDOCs and merge all together in an unique scene, and try to build the mesh with them?
Thanks.

Hi Victor,

I don´t really see the point.
You will need to wait until the end frame of each sim finished, cache that as an initialState, and then save that as the simulation to be send to a different node. But, how would that be useful?
And we are talking the same domain, not multiple domains, which I believe is what you were trying to simulate using different IDOCs, am I correct?

Hi, thanks for your reply. I will work with only one machine for the main simulation, but i still have some issues.
If you look at the scene_distibution picture, the emitter is animated alongside the terrain, and at the end of the shot, you can see the towers of water that is a fail in the simulation, and i'm trying to solve it.
How can i restart the simulation from frame 800 without lose the beginning part, from 0-800? Which values in the emitter or daemons could i change to solve the towers issue?

Thanks a lot.

Hi Victor,

I send you a mail. Could you send us the scene to check here the daemons issue?. About IDOCS, my colleague Gustavo told you how they are working. I send you a couple of links to take a look at this.
