Settings in the TurbulenceFD tab of the CINEMA's preference dialog:

Default Cache Base Directory

Specifies the base directory to use for simulation caches on new TurbulenceFD objects (see Cache parameters below).

Autosave Project To Cache

If checked, the project file will be saved to the cache directory when a simulation is started. That way you always have a reference copy of the parameters and setup that were used to create a cache.

Automatically check for updates

Check for new versions of TurbulenceFD automatically. It is recommended to leave this option enabled, especially during the Beta phase.

When a new version becomes available, you will be notified so you can decide whether to update.

Ask before overwriting simulation cache

If the currently selected cache is not empty and you start a simulation, TurbulenceFD will ask before overwriting the cache.
