Lagoa Setup Surface Tension

Contains all the necessary Lagoa nodes to create a particle emission in which the particles have a high degree of surface tension. The default results are particles that quickly group together in a circular formation, like a drop of water.

You can choose the Particles Create Lagoa Particles Surface Tension command from the ICE toolbar to use this compound. See Creating Liquid with High Surface Tension [Lagoa Multiphysics Simulations] for more information.

Plug this compound's Execute output into a port on the ICETree node or in an Execute port on a Simulation Root node.

Tasks: Lagoa/Presets

Output Ports: Execute

Sim Quality	Sets the quality of the simulation based on the Substeps and Resolution data. Increasing this value increases the substeps and particle density, which increases the time required to simulate.
Passive Body In Name	Plug in the Out Name port of the object with which the points will collide. This object can be animated (deformation or transformation) or not. Passive objects are not affected by any type of force in the simulation environment. You can define each collision object's properties in its own Lagoa Set Collision Data compound.
Surface Tension	Sets the degree of tension between points on an element's surface which causes the element to compress to the smallest possible area. This makes particles form into a spherical shape when grouped together. If you increase the surface tension, you should lower the Inelasticity value because opposing forces can make the particles flicker.
Internal Pressure	Internal pressure acts like an attraction between points that are within a certain distance of each other. High values causes points to group together, such as to form droplets, filaments, and sheets. This is visually related to surface tension and thickening effects of a fluid. Values above 1 are not recommended because they are create fluids that are impossible to have in nature, and they can cause instabilities, which means that you will need to increase the Substeps value in the Lagoa Simulate Multiphysics node.
External Pressure	This pressure tries to retain the shape of the whole element's volume by pushing the points away from each other (like a repulsion force) to prevent compression, which is especially noticeable in fluids. To have compressible fluid, make the Internal Pressure value smaller than the External Pressure value. The more compressible the fluid is, the more space is between the points, depending on the Resolution when they are emitted. In this case, the point volume will look sparse because the points are trying to reach their ideal distance quickly. This is a visible effect with gases where molecules tend to be very far apart. This value should always be 1 or higher. However, values that are too high (such as 15 or 20) can cause jittering, which means that you will need to increase the Substeps value in the Lagoa Simulate Multiphysics node.
Gravity	A default gravity vector used by the simulator. This is the required defined gravity force used internally by the simulator, and needs to be separated from the other forces.
Density	Sets the density of the air — see Lagoa Air Wind.
Force	Defines a force value to be applied to the particles. You can connect any of the force compounds into this port, or you can type in XYZ values to create a general force if nothing is plugged in here.
