I am running Fluent on batch mode by the commands below. I cannot find the output file after finishing the running and which software I need to use to read the post simulation for Fluent?

; Read case file
rc example.cas
; Initialize the solution
/solve/initialize/initialize-flow
; Calculate 50 iterations
it 50
; Write data file
wd example50.dat
; Calculate another 50 iterations
it 50
; Write another data file
wd example100.dat
; Exit Fluent
exit
yes

What output file you are referring to? The .dat files? Or the screen output containing all the residual information?


The .dat files are written in the working directory. If they're not there, you have to check the log to see why it was not written.


For the log... It is not controlled in this script but in the command you used to launch Fluent in batch mode.

I mean the .dat file.
If in GUI ANYSYS Fluent I run Initialization to get the .dat file for in an input file of journal file (at that time rc inputfile and rd inputfile). What is different between the .dat file created by run Initialization and the .dat file of output when finishing the batch mode.

And the second thing I am confused that how can I run a other simulation from the last time step of the previous simulation because I don't run to from initial condition. How to rewrite the command

/solve/initialize/initialize-flow
; Calculate 50 iterations

The only difference is the solution values that are saved in the file.

Remove the initialize line since you don't need it anymore. And add a line to read the .dat file using rd (rc is read case, rd is read dat, rcd is read case and data).

rc example.cas
rd example50.dat
it 50
wd example100.dat

You must remove or comment out the initialize line, otherwise that will re-initialize and erase all your solution data.

After running the Initialization, the the .dat and .cas file do not include the Calculation Activities such as Autosave (Every time steps), File storage option. So, how can I set up the Calculation Activities in a batch mode?
