You cannot have multiple emitters on a fluid cloud. As well, the Fluid operator works only with the default cube, disc, or square emitter objects.

Execution State
|
Mute |
Toggles the fluid simulation on/off. |
Range
|
Start Frame |
First frame at which the fluid simulation is calculated. |
|
Duration |
Number of frames over which the fluid simulation occurs. |
|
Copy from Scene |
Copies the start and end frame values from the scene’s timeline to the Start Frame and Duration. |
|
Copy to Scene |
Copies the values you set for the Start Frame and Duration to the scene’s start and end frame values on the timeline. |
Simulation Factors
|
Accuracy |
Sets the accuracy of the fluid simulation. Increasing this value controls the simulation more but takes more time. |
|
Slave Ratio |
The percentage of slave particles in relation to master particles that are set with Mean distance. A value of 1 means that there are as many slave particles as there are master particles. The slave particles are randomly distributed on the surface/volume of the emission. |
|
Mean Distance |
Density of the particles determined by the distance between them in a set space. This determines the number of master particles. The lower this value (the smaller the space between particles), the greater the density of particles. |
|
Foam % |
Determines which percentage of the particle density will be used as foam. Particles whose density is lower than the value here and with a value higher than the Foam speed min. are rendered as foam. |
|
Foam Speed Min. |
Determines which particles may be rendered as foam. Particles whose speed is higher than this value could be rendered as foam. The Foam % is also taken into account: particles with a density lower than that value will probably be rendered as foam; if a particle is not very “quiet,” it will probably be rendered as foam. |
|
Output Sequence |
Name of file in which you want to save current particle simulation. The file extension is .ptp. By default, these files are saved in the c:\temp folder with the prefix “Fluid.” If Usr is on, the path is displayed as you entered it. If Res is on, the resolved path is displayed. |
|
Clean Cached Files |
All the PTP files that were recorded and cached for playback are erased each time you exit Softimage. PTP files record the position of your particles at each frame in the animated scene. |
|
Restart from File |
Restarts the simulation from a previously selected PTP file. Select the file you want before selecting this option. |
Collision Accuracy
|
Iterations |
The number of times a particle’s position is calculated per interval. The higher the value, the more accurate the position but the longer the time it takes to calculate. |
|
Interframes |
The number of times a particle’s position is calculated per frame. The higher the value, the more accurate the position but the longer the time it takes to calculate. |
