Planetary impact simulation failing after random amount of time: "error: [05595.1] xmf.c:xmf_prepare_file():86: Unable to open temporary file" about swift HOT 4 CLOSED

Hi Matt,
that report is a little misleading, it really means that the temporary file could not be created. So the usual reasons for that are trying to open the file when your quota is exceeded, the directory has been moved or deleted, the permissions have changed etc.

One other possibility is a contention issue, that is the file is being used by more than one process. This could happen if you are running multiple jobs from the same directory, or you are running SWIFT using mpirun/mpiexec but are running the non-MPI binary by mistake. This latter way is the only time I have seen this message.

@mjr230600 did that work for you?

The problem seems to have been resolved and was potentially due to changing the partition that I was using on the computer I was running the sim on here at Bristol. Thanks for checking in though!

Glad it's all solved! :)
