An IDOC is an acronym standing for “Independent Domain Of Computation”. If you look under the grid fluid icon, you can see a total of three entries: “Splash per IDOC”, “Foam per IDOC” and “Mist per IDOC”. Another location for IDOCs can be found right to the RealWave icon. From this menu you can add IDOCs for both standard and grid fluids, and simulate them over your network. This method is perfectly suited for side-by-side comparisons, for example.
Left image: fluid interaction without IDOCs; right image: fluids inside IDOCs simply go through each other.
The idea behind IDOCs is that you can perform multiple simulations within a single scene, but on different machines. The most important aspect with this node type is that the emitters are calculated separately from each other. This means that RealFlow does not simulate interactions between the IDOCs, respectively the individual emitters. For that reason it is possible to simulate emitters, which are encapsulated in IDOCs, over a network on different computers. This principle works for both Hybrido secondary elements, the so-called HySPH emitters and standard particle sources – the SPH emitters.

Furthermore, please note that network simulations can only be performed with an appropriate number of licenses. For each computer you want to use, a “RealFlow Node” license is required. With a standard “RealFlow GUI” license, network simulations are not possible.

IDOC – Basic Workflow
Here, a typical Hybrido scene is prepared for splash generation and subdivided into multiple independent areas – the IDOCs. The mode of operation is almost the same for standard particle emitters, but for Hybrido's secondary elements there is a very convenient way of attaching the emitters to IDOCs with a single click using the “Splash per …” functions from RealFlow's Hybrido node set.
When you use IDOCs for Hybrido simulations, a core fluid is required where you add splashes and foam. Only these HySPH elements can be simulated with the help of IDOCs, while the underlying, main body of fluid (the actual grid fluid) has to be generated on a single machine. With standard SPH emitters, the IDOC method can be used from the very beginning.
