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.

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
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′);
3. run the commands in the batch file from Matlab, mixed with your Matlab commands. See below some examples
4. When you are done you can shutdown Fluent from Matlab:
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.
