You can render a fluid simulation using many different renderers. Most require a cached or dynamic mesh in order to process a result.
For more information, consult your renderer documentation.
Adding Channels
You can add channels that are generated during the simulation to your mesh. These channels can be used at render time for various operations such rendering with motion blur or creating a custom channel that can be used in maps of the liquid's material. When using dynamic caching, these channels can be added at any time. When using a cached mesh, you must add the channels before caching.
The added channels have no effect in Arnold Surface or Arnold Points. Arnold Surface and Arnold Points get their data directly from the .bif cache file.
Rendering with Arnold Surface and Arnold Point
Arnold Surface and Arnold Point is the recommended solution for rendering fluid simulations. Unlike the cache mesh render option, Arnold Surface and Arnold Points procedurals are generated directly within the Arnold renderer itself. This offers the highest quality and most efficient solution. For more information on using Arnold, see the 3ds Max Arnold documentation.
