Hi Taes,

I will advise you to use actfluentserver instead.

Please read the blog below for more detailed information.

Hi,

I'm using now Im using AAS- to couple Matlab (2018b) and Fluent (2019R2) and use it as a Server. I have followed the steps in the official Ansys Youtube tutorial for the connection, and have read the users guide: "Fluent as a Server".

Most of functions seem to work such as: tui.doMenuCommandToString(), fluent. getNrInputParameters(); fluent.getInputParameterNameByIndex(in long lInputParameterIndex);

Nevertheless, the most important functions that I need do not work: (WRITE AND READ PARAMETERS of Fluent)



fluent.getOutputParameterValueByName(string('q_rad _thorax'))

fluent.setInputParameterValueByName(string('T_head '), 200)



I write an example of what Im coding:

%%%%%%%%%%%%%%% CODE %%%%%%%%%%%%%%%%%%

%% Basic Connection %%%% RUN THIS SECTION - Once per matlab session



orb=initialize_orb();

load_ansys_aas();

fluent=actfluentserver(orb,'aaS_FluentId.txt');

tui=fluent.getSchemeControllerInstance();

tui.doMenuCommandToString('report summary')

%tui.doMenuCommandToString('define operating-conditions gravity yes 9.8 0.0 0.0');



fluent.getOutputParameterValueByName(string('q_rad _thorax'))

fluent.setInputParameterValueByName(string('T_head '), 200)

%%%%



MATLAB OUTPUT ERRORS:



>> fluent.setInputParameterValueByName(string('T_head '),200)

Java exception occurred:

AAS_CORBA.EFluentGenericError: IDL:AAS_CORBA/EFluentGenericError:1.0
at AAS_CORBA.EFluentGenericErrorHelper.read(EFluentGe nericErrorHelper.java:80)
at AAS_CORBA._ICoFluentUnitStub.setInputParameterValu eByName(_ICoFluentUnitStub.java:456)



>> fluent.getOutputParameterValueByName(string('q_rad _thorax'))

Java exception occurred:

AAS_CORBA.EFluentGenericError: IDL:AAS_CORBA/EFluentGenericError:1.0
at AAS_CORBA.EFluentGenericErrorHelper.read(EFluentGe nericErrorHelper.java:80)
at AAS_CORBA._ICoFluentUnitStub.getOutputParameterVal ueByName(_ICoFluentUnitStub.java:579)



PD: I have already written in my Fluent case these parameters previously, so they exist. I have also tried writing fluent.getOutputParameterValueByName('q_rad_thorax ') and neither works. The error that I get from at FLUENT command window: unbound-variable, set-parameter-data



Thank you very much,

Any help would be really welcome.

As obvious I couldn't find a dll in the Linux installation folder :-)).

So I think I have to compile the idl file myself, but I do not know which compiler should be used to drive Fluent-aas from Matlab.

In my System:

Matlab is running on a Linux 64 bit machine.
Fluent is running on a 64 bit network accessible remote machine.
Fluent Version is 15.0

Thanks for youre help in advance.

Hi!

I have exactly the same problem and was wondering wether you found a way to work around this? Or is it only possible with that Matlab extension in the blog?


Kind regards,
Carlijn

Hi Carlijn,

Did you figure out how to get it working on a linux OS?

Yes! I figured it out. What I eventually did, was using the ANSYS_aas MATLAB Toolbox which is provided by Ansys. In order to use this I had to use an older version (the 2015 version) of MATLAB. After installing it once I could operate Fluent within Matlab on my linux computer with the following lines:

% launch Fluent
pathToFluent = ' "/share/apps/ansys192/v192/fluent/bin/fluent"';
args = ' -v2ddp -g -aas -i JournalModel.jou &';
[s, out] = system([pathToFluent args]);

% wait for fluent aas file to be generated and the journal file to be read
pause(90)

% do the actual coupling
orb=initialize_orb();
load_ansys_aas;
fluent=actfluentserver(orb,'aaS_FluentId.txt');
tui=fluent.getSchemeControllerInstance();

tuiCommand=['/file/interpolate/write-data "',SigmaPath,'/InterpolationOutputFile.ip" n y-velocity x-velocity pressure () n'];
tui.doMenuCommand(tuiCommand);

Hope this helps you!

ps. Sorry for my late response, the message ended up in my junk mail box, so I hadn't seen your question
