Hi all,
I have so many design points to study effects of some parameters on thin film deposition in CVD process. I follow this procedure in fluent :

1. model ==> species model ==> volumetric and wall surface both off

2. solution initialization

3. run calculation ==> until continuity equation is converged.(flow without reaction)

4. model ==> species model ==> volumetric and wall surface both on

5. run calculation ==> 200 iteration (as convergence criterion is none)(flow with reaction).

As shown, it is required to set each step manually, so the procedure takes around two hours per each design point. My question, is there an efficient procedure to solve many design points for flow with reaction in fluent. thanks

Learn how to use TUI commands and write a journal file to do exactly those steps.

Just press enter/return in the TUI and get a list of available TUI commands.

Hey LuckyTran, Thank you for replying, I appreciate that. I did : file ==> start journal , following the procedure that is mentioned above, then file ==> stop journal. When I started the program again, file ==> read journal file. It is just read the last two steps !! any suggestions please

For your own benefit, I recommend you do not use the record macro function and actually learn how the TUI works. It looks like a daunting task and looks like learning a programming language but it's actually not that deep. The benefit in Fluent at least is that you have an interactive environment and you can see the consequences of each TUI command immediately. And you can always see a list of available commands by simply hitting enter. Anything you want to do in the GUI has a corresponding TUI command.

For example to do 100 iterations you just do
/solve/iterate 100

To read a case and data file it's just
rcd blah.cas
To write/save
wcd blah.cas y (the y is short for yes to overwrite)

The modelling options you want can be found in
solve/set blahblahblah
or
/define/model/ blahblahblah
