Hi all,

I am trying to couple fluent and matlab to be able to automate simulations in fluent using matlab. I am using the matlab aas toolbox to do the cosimulation and I understand you can use it to run single commands. But my question is whether or not it is possible to use it to run a whole journal file. I want to get a journal file, change it a little bit in matlab and then run the journal file in matlab to perform the simulation in Ansys.

Thanks

A journal file is nothing but a a text file which contains a bunch of TUI commands which Fluent reads/interprets and executes. If you can run any TUI commands from matlab, then you are all set. You don't "run a journal file" per se, because it's not a program.

Hi lucky,

Thank you for the quick reply. I understand that a fluent journal file is just a bunch of commands. The thing that confuses me is that because the aas toolbox allows matlab to send one command at a time, can it not send more than one command at a time?

Sorry, I guess I took this statement too literally. I guess you meant to say that you will use aas rather than you currently are using it.

The AAS toolbox launches an interaction session of ANSYS. Practically, this lets you do virtually anything from matlab. If you have AAS working... it should be readily apparent.

Hello,

There's an error. I have initialized the model as required. It works right without AAS mode enabled. But when I set FLUENT for AAS, same error pops up as shown in images with both "FLUENT solution update" or "iCoFluentUnit.calculate() command call on MATLAB". Can you please clarify on this? I tried resolving this with exception management but no luck.

Thank you,
