Thank you Charles, I can now run the project on the computing cluster, and I want to know how can I specify at the same time mfixsolver -f -c. For the sbatch script, it said the -c can not be recognized as follows. Thank you in advance.
The -c flag is only supported by the interactive (Pymfix) solver. The batch (pure Fortran) solver does not support the -c flag. If you need to clean up output files from a previous run, you will have to add a command to the script - either do this by hand before starting the run, or add something like
rm *.OUT *.VTP *.LOG
to your job script
