GAMBIT Batch Mode - MATLAB
 

I am trying to exectue GAMBIT through MATALB with !gambit, however i am then required to physically click on "run" to open the program. Is there a way to bypass or automate this within MATLAB?

Re: GAMBIT Batch Mode - MATLAB
 

Try :

>>system('gambit -inp journalfilename') from Matlab.

infact

>>! gambit -inp journalfilename still works for me without system command.

Hi,

I'm working on the batch mode process too. Though the command works fine, gambit doesnt open a new window when it is creating a new design. Because of this, it is creating overlapping geometries and hence I'm getting a lot of errors like "walls already exist, zones already exist" etc..

What do I do to overcome this ?

Thanks

Hello,

I am trying to link Gambit with Matlab, but I am getting the following error in Matlab. I am using !gambit.exe -inp c1.jou

Can anyone explain why?

'gambit.exe' is not recognized as an internal or external command,
operable program or batch file.

Either delete all the old gambit project files between each run or have each case open with a new name.

You need to modify your environmental variables so that the Gambit executable is in your path. Right click "My Computer" -> Properties -> Advanced System Settings -> Environmental Variables and then add the directory which contains the gambit executable to $PATH.

Hello
I did this and set environment variable but there is a new problem,when in my matlab m-file i write "!gambit.exe -inp test.jou", gambit begins to start just for a moment but suddenly it jumps out and nothing happens then,but when i write in my matlab m-file this :"!gambit.exe" without -inp ,exceed and gambit begin to start and then comes this window (attached picture) that wants me to push the "run" button and when i push it gambit runs correctly but of course without opening my journal file. the point is i am doing an optimization work and i need gambit run in an automated way,i don't want to push the run button every time and i need gambit to run my journal file automatically without my interference. do you have any idea what is wrong with what i do?
thanks in advance

You need to check the gambit command line parameters (you can set up the home directory, the graphic server etc ...), this will get rid of the graphical window. Try in a command window something like:

gambit -h
gambit --h
gambit -help
gambit --help

Hopefully one of the above should work.

Do

thanks for reply,i did as you said but the graphical window appears again, I am not sure but i think the problem is with linking between exceed and gambit,because when i try to use "!gambit.exe -inp test.jou" in my matlab m-file there is no exceed running,in fact it happens like this:gambit startup menu appears for a second(like the attached picture below) without any exceed appearing(as you see in the picture it seems journal file has been run correctly because edges are created and it has reached to Command>end) then it jumps out,but when i use "!gambit.exe",start up menu appears then i push run button,then exceed runs,and finally gambit GUI appears.

I've successfully automated Gambit in MATLAB using batch processing for the purposes of optimization like you said, so yes it can be done. And like the above posts say, all you do is clear any previous "default" files which contain geometry and use gambit. I use linux, so my code is:

!rm default* myTurbine.msh*
!gambit -inp makeTurbine.jou

If you're having problems then you are probably right that the issue is with Exceed. Can you start up Exceed prior to going into MATLAB? I remember doing that when I used Gambit/Fluent/MATLAB on Windows; I'd have Exceed up and it did not shut down when each batch run completed.

Hi,

I've done it with windows. Exceed must be opened before starting. My matlab file is able to produce a file ".txt" used as a journal for gambit and later open and run gambit automatically. Use this and use attention for your file path:

! C:\Users\Administrator\Desktop\gambit\Fluent.Inc\n tbin\ntx86\gambit.exe -inp gambit.txt

Batch mode
 

Dear Gholamghar,

I encountered with the same problem (starting Gambit in batch mode). When I start Gambit using command prompt or matlab, startup window vanishes immediately after appearing.
Could you manage to resolve this problem?! if so, would you let me know how you overcame this?

tnx

using matlab to gambit run
 

Hello everyone

Due to the use of Gambit to produce mesh, this command can be used on matlab m_file :

system(' "gambit source working directory" -inputfile " gambit_journal working directory"')

for example:

system('"C:\Fluent.Inc\ntbin\ntx86\gambit.exe" -inputfile "C:\matpg\pmesh.jou"')

Therefore by using this code on matlab, gambit automate runs and acts accordingly journal file.

Good luck:)
