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.
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.
- Nodes from different IDOCs behave as if they were disconnected.
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. Here 2 x 2 IDOCs in horizontal direction will be added: XY or XZ – this depends on your → axis setup.
- Hit OK and "Cube01 will be used to subdivide the simulation space. It is safe to delete "Cube01" afterwards.
You get four IDOCs, represented through green boxes:
Adding The Splash Emitters
There is a very convenient way to create and scale IDOCs for Hybrido secondary emitters automatcially. Go to the IDOC shelf and click on the "Splash per IDOC" icon:
- Set "HY_Domain01" to → "Cache" (yellow rocket symbol) to prevent the core fluid from being re-simulated.
- Save the scene.
A shortened view of the "Nodes" list with the attached splash emitters, and "HY_Domain01" set to "cache".
Distributing the Simulation
Now, the scene can be distributed:
- Launch the “Job Manager” and "Job Node" applications.
- Open the "Job Manager's" → web interface under Layout > Job Manager (if the interface is blank click on the "Home" button).
- Select the IDOCs from the “Nodes” panel and click on IDOC > Send to job manager.
The IDOCs are added to the job queue in the manager's GUI and the simulation will start automatically:
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.
- Start the simulation with IDOC > Send to job manager.
