Large volume fluid sims

[mishurov]

How to simulate the large scenes with many smoke objects by a network machine using hbatch or hython? If one lores smokeobject, I just render the Dop I/O to files nevertheless If there are many lores and hires smoke objects, I can't render that at once cause there're many ROP nodes in scene, each for one of the smoke objects. How to simulate a scene such as the described below one using hython without rerendering or resimulating it many times?

I hope you've understood me. It's quite hard to me to write in foreign language

There are many ways this could be done depending on how you want to handle the workflow. Multiple pyro/smoke objects can be plugged into a single solver with a merge node if you want all of the objects to simulate at the same time. Then grab out the pyro/smoke objects with the DOP I/O node and merge them back together before plugging into a ROP Geometry node. If you want to simulate each on their own then just make a ROP Geometry driver for each DOP I/O and simulate one at a time or send each to a farm with a queue manager (like HQueue).

EDIT: Another way would be to use a File DOP node to write out the simulation cache in the DOP instead of caching out the geometry from the simulation at SOP level.

I suppose If you want a good answer, ask a neat question. Kindof. I'm already found a solution with hython and file DOP. I'd thought, however, that file DOP doesn't contains whole network, data'n'objects I mean. Smoke object is reading his fields after solver has done all substeps.
