An IDOC (“Independent Domain Of Computation”) is used to subdivide a project's simulation nodes into spaces. Only nodes, which are attached to the same IDOC, are able to interact. In this workflow example, the result from a → Hybrido core fluid simulation is used to create four IDOCs, and simulate splashes via a network.
Before you start you have to → license and → configure RealFlow's network components.
Creating the IDOCs
- Define the entire simulation area by enclosing it with a bounding cube ("Cube01") – keep the cube selected.
- IDOC shelf > Multiple
- A new window appears where the number of IDOCs is defined. Here 2 x 2 IDOCs in horizontal direction will be added: XY or XZ – this depends on your → axis setup.
- When you hit OK then "Cube01 will act as a template to subdivide the simulation space. It is safe to delete "Cube01" afterwards.
You get four IDOCs, represent through green boxes:
Adding The Splash Emitters
If you want to connect Hybrido secondary fluids to IDOCs then there is a very convenient way. Go to the IDOC shelf and click on the "Splash per IDOC" icon:
- This one-click action creates, places, scales, and attaches the splash emitters automatically.
- Now set "HY_Domain01" to → "Cache" with the small rocket symbol under "Nodes" to prevent the core fluid from being re-simulated.
- Save the scene.

Distributing the Simulation
Now, the scene can be distributed:
- Launch the “Job Manager” application.
- Start the “Job Node” program on every licensed computer.
- Open Layout > Job Manager - an interface to monitor the simulation's progress.
- Select the IDOCs from the “Nodes” panel.
- Click on IDOC > Send to job manager.
The IDOCs are added to the job queue and the simulation will start automatically.
Important Annotations
IDOCs are not restricted to Hybrido secondary fluids, but they are the most common field of application. In fact all of RealFlow's simulation nodes can be used with IDOCs:
- All nodes which should be able to interact must be attached to the same IDOC.
- You can also attach more than one emitter to a single IDOC and these emitters will be able to interact – as long as they are of the same kind (SPH-SPH, Dyverso-Dyverso, etc.).
- There can only be one RealWave node per scene, but → “Object Splash” and → “Crest Splash” emitters can be used with IDOCs.
Most of RealFlow's simulation nodes have to be attached to their IDOCs manually:
- Create a simulation node, and place (W) it inside its IDOCs.
- Connect node and IDOC in the → “Relationship Editor” - just press the Ctrl/Cmd key and draw a line from “IDOC0X” to its simulation node.
Once you have prepared the scene's setup, send the IDOCs to the "Job Manager",
