Hi there,
I have a problem in running fluent as a batch mode using Matlab, I am using the following command !C:\Fluent.Inc\ntbin\ntx86\fluent 2ddp -hidden -i "./FNACA4412.jou" But I always end up with an error massage of: Error: read-data: invalid plot file format Error Object: *eof* Warning: An error or interrupt occurred while reading the journal file. Some commands may not have been completed. However, if I open fluent and used; file/read-journal ... and selected the journal file it will work perfectly..!!! Please help and advice. Thanx FH. |

Hi F.H.
Did you try using Fluent in server mode? Instead of starting Fluent from inside Matlab you can start it from outside Matlab (could be on a different machine) and then connect from Matlab. You can run the TUI commands from the connected Matlab one at a time. See below an example (I presume you are using Fluent R14.5...) 1. Have the Fluent COM connector registered to Windows cd C:\Fluent.Inc\fluent14.5.0\addons\corba\ntx86\ regsvr32 ComCoFluentUnit.dll 1. start Fluent in server mode with the following command: C:\Fluent.Inc\ntbin\ntx86\fluent 2ddp -aas Fluent will generate a server key (aaS_FluentId.txt) in the folder where you launched Fluent 2. start Matlab and execute the following commands to connect to Fluent's TUI interpreter using aaS_FluentId.txt fluent = actxserver(‘ANSYS.CoFluentUnit.1′); tui=fluent.getSchemeControllerInstance(); fid=fopen(‘aaS_FluentId.txt’,'r’) fluentkey=fscanf(fid,’%s’) fclose(fid) fluent.ConnectToServer (fluentkey) 3. run the commands in the batch file from Matlab, mixed with your Matlab commands. See below some examples tuiCommand="report summary" tuiOutput=tui.DoMenuCommandToString(tuiCommand); rpVarName='pressure/relax' rpVarValue=tui.GetRpVar(rpVarName) ... 4. When you are done you can shutdown Fluent from Matlab: fluent.Terminate() You can find all commands in the ANSYS Fluent aaS documentation. For a small example you can refer to my blog post at http://www.ansys-blog.com/tag/matlab/ Please let me know if you need more info. Sorin |

Hi, thank you for your tips,
I have a problem in the first line. fluent = actxserver(‘ANSYS.CoFluentUnit.1′); I have an error : Error using actxserver (line 91) Server creation failed. Invalid ProgID 'ANSYS.CoFluentUnit.1'. |

fluent = actxserver('ANSYS.CoFluentUnit') worked for me. I was able to run FLUENT and pass TUI commands from MATLAB this way. |
