Dear all,
I'm trying to run multiple cases using ANSYS Fluent CFD where I can leave my simulation computer runs overnight?
Thanks
If you have multiple licenses and enough CPUs, you can open multiple ANSYS workbenches and run them simultaneously.
OR, if you mean you want to run multiple cases with different parameters, you can google 'FLUENT parameteric study' or else.
Dear Donghyun Kim,
Thanks for your response.
Actually, I have the same case but with different velocities at the inlet. I want ANSYS Fluent to continue running (let's say for 3 velocities) and record the results at each velocity separately.
I'll try to follow your suggestion and see if it's possible.
Hi Mohammed Amer
One easy way to do it is to use journal/scheme programing. A journal file contains a sequence of commands. You can write it in the TUI, or write it in a text file and read it from GUI (read journal). Please refer to this page for some examples of using journal file (the one for batch simulation suits your needs)
https://www.cfd-online.com/Wiki/Fluent_FAQ#How_do_I_run_multiple_cases_in_batch_mode.3F
I personally start a case and set it for few (10) iterations. Then follow this steps to write a journal file automatically using write
1- open the first case,
2-initialize
2-start journal
3-set the boundary condition (e.g. Vin = vel1)
3-When the iterations are done write the data and name it (e.g. vel.1.data) (or save any desired parameter over any domain/surface, which can be done when you are done with saving the results)
4-stop journal.
Now, you have a text file containing the commands. Go ahead and modify the iteration number. Then copy all of it and append it to the end of your text file for your other cases with their corresponding BC and save name.
Once done. open the main case file and read the finalized journal
Dear Shayan Davani,
Sounds great. I'll check your suggestion and see.
Thanks in advance.
