Time Scale

This value controls how fast time will pass for the simulation. At 1.0, the simulation will run at the same speed as the animation. Values below 1.0 slow the simulation down, values above 1.0 speed it up.

You can for example animate this value down to 0.0 to create bullet-time-like animations.

Frame Range

specifies what part of the time-line to simulate.

This corresponds to Lightwave's Preview Range and Render Range.

Start Clean Simulation

Clear all channels before starting the simulation at the frame specified above.

Load Simulation State From File

If Start Clean Simulation is unchecked, channels will be initialized from the file specified here. The file may be any .bcf file from a TurbulenceFD cache directory. Channels that are not available in the .bcf file will be cleared as if Start Clean Simulation was checked. See the parameters in the Cache tab for information about how to control which channels are saved to the disk cache.

Continue Simulation From File

If checked, the next simulation run will load the state from the file specified above and jump to the frame following the one cached to the file. Use this to continue a simulation at any cached frame, possibly after changing some parameters.
