Hi,

On 3 occasions now (2 today), I've encountered a problem in which the Constant file is deleted in my case folder as the case is running, causing it to fail.

I think it could be occuring during the writing of files, because as far as I can tell on both occasions today it happened on a time-step that was being saved. I don't know if available storage has anything to do with it, but while I am low-ish on space, I still have around 10-20GB available.


Has anyone ever encountered this before, or know what it might be? I can't find any mentions of this problem online. I can't think of anything I have changed in the last day or two.


Potentially useful information: OpenFOAM version 5. SFRSimpleFOAM case, parallel, deconstructed over 16 cores.

Thanks in advance, I'm very confused by this, and any insight would be really appreciated.

Edit: This happened again today. Again it seemed to occur at a time-step that was being saved, although I freed up plenty of space on the hard drive so I don't think lack of space is an issue.

In case it is something to with how files are being saved, here is my ControlDict file:
