data transfer between fluent and matlab

ss_stardust · December 4, 2021, 14:02

Hi all,
I am using MATLAB AAS toolbox for connection between fluent and MATLAB.
Now, I need to use FLUENT for simulation and MATLAB for optimization. I want to send initial population calculated in MATLAB to FLUENT, run simulation in FLUENT for that initial population and return some numerical data to MATLAB such that process can repeat itself till convergence in optimization is achieved. How can a UDF/Scheme code be written so that this transfer can be executed automatically?
Thanks.

you may control fluent from matlab using

Code:

iFluentTuiInterpreter.doMenuCommand(*TUI COMMAND HERE*)

Thanks @AlexzanderZ for the quick reply.
To be specific, I want to use MATLAB inbuilt GA toolbox for optimization. So, I want to send the initial population of variables as input to my simulation in FLUENT and get output from fluent to calculate my objective function. Can someone please provide or guide for the Algorithm or workflow to achieve the coupling in above mentioned way along with possible macros/commands required for this workflow as I am a bit new in this area?

Thanks
