  Hello everybody,
  I'm currently in the process of completing some transient simulations in ansys fluent 2025R2. I'm using the University's HPC for those simulations and i need the output to be in the legacy format (.dat) rather than the CFF (.dat.h5) my journal file is as shown bellow. Can anyone help?
  
  file/set-batch-options , , yes ,
  
  file/read-case NAME.cas.h5 yes
  file/read-data NAME_result.dat.h5
  solve/set/data-sampling yes 1 yes yes
  
  file/auto-save/root-name "NAME-%n"
  file/auto-save/data-frequency 50
  file/auto-save/retain-most-recent-files no
  
  solve/set/time-step 0.001

  First off, always use the first / so /file otherwise you're executing the command from whichever menu level Fluent's in. Try:
  /preferences/general/default-ioformat legacy
