  I have been running a VOF-to-DPM simulation in Fluent 2021 R1 and have run into an error. I had a "Low Disk Space" error last week so cleaned up my C drive and freed up 275 GB of space. I am also auto saving to an external hard drive (with 450 GB of space). Today after three days of running, my simulation stopped running and produced the error in the question title. I have 32 GB of installed Ram with a 16 core AMD Threadripper Pro processor.
  For my domain, it began with around 250,000 cells but now have somewhere near 5 million last time I was able to see an update on the adaptive mesh.
  Any ideas what's happening? Seems like I should have enough memory, but maybe not?
  Thanks.

  You may have filled a disc somewhere, or the external disc link had an interruption. It's best to save locally and then move files as any network hiccup can cause saving errors. 5 million cells will need somewhere in the 12-20GB RAM depending on various things, but running out of RAM usually gives a malloc error.

  Rob Thanks for the help. It must be a network hiccup. Watching CPU, Memory and Disk stats in the task manager shows that the disk only reaches about 27% at any given time. I'll save locally and see if that helps.
  Thanks!
