"Vortex" creates a force field around the daemon's centre and along its vertical axis. Both forces can be adjusted independently. The closer the particles are to the axis, the faster the rotational motion will be.



 

RealFlow Scene

In RealFlow | Maya it is possible to use multiple "Scene" trees in the same project. To link a daemon to a different scene tree right-click on the field, choose "Set Scene", and select an item from the appearing list.

Linked Domains

All fluid, rigid, and elastic containers inside the field will be affected by the daemon. If there is only one container in the scene it will be linked automatically. Otherwise the connection has to be established manually.

Affect

There are two options:

  • "Force" accelerates the particles and they become faster and faster as long as the force is acting on them. 
  • “Velocity” only works with particles and adds the daemon's "Strength" value to a particles speed. The resulting peak velocity remains constant during the simulation.
    An example: Let's assume the daemon's "Strength" is 9.8 and the emitter's "Speed" value is 2.0. Here, a particle's velocity will be roughly 11.8 m/s.
Rot Strength

This is the strength of the rotational force around the daemon’s centre axis. “Rot Strength” accepts positive (clockwise) and negative (counter-clockwise) values.

Central Strength

The centre axis can create an attraction (positive) or repulsion (negative) force.

Attenuation

You can choose from three fall-off types: “Linear”, “Squared” and “Cubic”. The fastest attenuation is achieved with “Cubic”.

Bounded

With “Yes” the "Vortex" daemon is displayed with a stack of three rings around the axis. The radius ("Boundary") of these rings determines the zone of influence.

Boundary

Here the radius of the zone of influence is adjusted.

Vortex Type

“Classic” creates a homogeneous force field, where the fall-off obeys the adjusted “Attenuation”. With “Complex” the forces reach their peak strength at a given distance (= “Radius”) from the centre. This distance is displayed as a dashed circle line around the centre.

Radius

To use this setting, ”Vortex Type” must be set to “Complex”. “Radius” determines the distance from the vortex centre where the forces reach their maximum.

Bound Sup

This is the upper limit of the vortex.

Bound Inf

This is the lower limit of the vortex.
