When I push the resolution of my fluid sim to say 300 or more it will run for a while - about an hour then just quit, no errors. The remaining frames are not simulated and the domain turns back to a solid cube in those frames. At lower res it works fine. It does the same in blender 2.79 and 2.80. Not sure whats going on...


Pretty sure you ran out of memory. The fluid sim is a notorious memory hog, and most users do something to "fake" more detail in fluids. Bit of a bummer because it takes a very beefy system to make liquid that doesn't look chunky and gross.

I think there's a project to improve this somewhere...

  • $\begingroup$ Thanks for the info. I have a beefy system 16gig of ram + 8 of swap so I don't think so. However ill dump memory usage to a log file all night and see if that's indeed happening. At the start of the sim however I have 10gig free. $\endgroup$

  • $\begingroup$ No that's truly ram. These are exponential. $\endgroup$
