Good evening,

Im using AAS- to couple Matlab and Fluent 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(EFluentGenericErrorHelper.java:80)

 

at AAS_CORBA._ICoFluentUnitStub.setInputParameterValueByName(_ICoFluentUnitStub.java:456)

 

>> fluent.getOutputParameterValueByName(string('q_rad_thorax'))

Java exception occurred:

at AAS_CORBA.EFluentGenericErrorHelper.read(EFluentGenericErrorHelper.java:80)

 

at AAS_CORBA._ICoFluentUnitStub.getOutputParameterValueByName(_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. Here below I attach 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.

Hello,nI have similar problem. I'm using Matlab 2017b and Fluent 2019 R1. When I try to run Fluent calculation by command: n>> iFluentTuiInterpreter.doMenuCommandToString('solve iterate 100')nIt starts calculation but immediately Matlab gives an error and calculation stops:nJava exception occurred:nAAS_CORBA.EFluentGenericError: IDL:AAS_CORBA/EFluentGenericError:1.0n at AAS_CORBA.EFluentGenericErrorHelper.read(EFluentGenericErrorHelper.java:80)n at AAS_CORBA._ICoFluentSchemeControllerStub.doMenuCommandToString(_ICoFluentSchemeControllerStub.java:126)nnIs there any solution?nThank younJann

Is this the video you're looking at?

Do you have access to the customer portal to download the example files? I'm not sure what the issue could be at this stage
