basically you can use text command...
; Read case file
rc example.cas
; Initialize the solution
/solve/initialize/initialize-flow
; Calculate 50 iteration
sit 50
; Write data file
wd example50.dat
; Calculate another 50 iterations
it 50
; Write another data file
wd example100.dat
; Exit FLUENT
exit
yes

but there is a command that write journal file from an exist simulation?

i have read to fluent's manual and it explain to use write journal file and then stop journal file.
so i thinking that fluent recorder the next operation; is it?

you can create a journal file from Fluent:
before setting your case, go to file/write/start journal...
Then set up your case, once you are finished, go to file/write/stop journal...
Fluent should write everything you did in a journal file, which you can now read and reproduce.
hope it helps
