is there anyway to export the fluid files to external programs? I know I can export each frame as a mesh but this seems an incorrect way to go.
thanks for any info.


Incorrect? It’s the only way. Fluid are really a mesh per frame animation in blender. If you wan to export in other application, the only way would be to script it to extract and load each bobj file for each frame in animation.

Depending on the application you’re thinking of, it might be possible to directly load the .bobj files. They’re basically a simple binary mesh format. I had a small Blender python script to load them:
That could help as an example how to load one of them.
