Now you are ready to → add the scene's nodes. Here, we want to start with a very basic → Dyverso fluid simulation:

Additionally, you have to specify where the fluid will be created. This is the point of particle emission is determined with an emitter:
The Dyverso "Circle" emitter icon.
...
- Dyverso - Particles shelf > Circle
- A circle-shaped icon with an arrow appears in the viewport. The An arrow indicates the emission direction (see image below).
- With the E key it is possible to rotate the emitter, the W key is used to define a new position.
- Additionally, a domain node (HY_Domain01) is created. The domain is responsible for the number of particles ("Resolution" parameter) and the fluid's physical characteristics like density or viscosity.
The emission direction arrow.
Adding Interaction Nodes
We want the fluid to fill a vase. To do that, two more nodes are needed:
...
- Daemons shelf > Gravity
- This node accelerates the fluid and makes it fall.
- Objects Geometry shelf > Vase
- Rescale the vase with the R key and reposition/rotate the "DY_Emitter01" node, if necessary.
Relationships
Please check if all scene elements are properly connected via a "Hub01" node in the → "Relationship Editor". In this configuration the fluid will be able to collide with the vase and the daemon attracts the particles. Without these connections you will not see any particles. If the lines and the "Hub01" icon are missing please add a → "Hub" node from the panel's icon bar. Then connect the nodes as shown below by dragging lines between the icons with a pressed Ctrl/Cmd key. Also make sure that Edit > Add > Add to Default Hub is active. With this option all new nodes will be linked via a "Hub" automatically to establish global connections.
This is already everything and you can press the → "Simulate" button:
...
In oder to create more particles go toactivate the "HY_Domain01" node:
In the "Node Params" panel open the "Particles" tab:
- DY_Domain01 > Node Params > Particles > Resolution > 50.0
- Now, the fluid will be "denser" and you will see more details.
- A more natural look of the fluid is achieved with
...
- DY_Emitter01 > Node Params > Circle Emitter > V | H random > 1.0
- These the settings from the image below. These parameters remove the regular emission pattern.
Most probably you will see a gap between the vase object and the fluid particles. Here is how to improve the quality of the interaction:
- Vase01 > Node Params > Volume > Cell size > 0.02

view).
Of course, you can add other daemons, e.g. → "Wind" or a → "k Volume" daemon in oder to delete escaping particles. Play with the "DY_Domain01" node's settings to see how the fluid will react to your changes.
