How to increase Stack Size when starting ANSYS Batch?

Dear all,

I am facing problems when trying to perform an Ansys calculation via a Batch file started from Matlab. I simply start the Batch file like this:

system('"BATCH.bat"');

Ansys starts bulding the model and ends just when starting to calculate the model. If I start the Batch file directly from the cmd there is no problem. Evene starting it with VBA from Excel it works fine. I even tried the way to start the vba command in excel from matlab, this failed again.

So I guess it has to do something with how Matlab starts the Batch file or any other external programm. Is there any space restrinctions built in the system command?

I have read something about increasing the stack size to improve Ansys Performance. The FE-Model is quite big. So how can I increase the stack size in the system command call?

I am using MatLAB R2016a, ANSYS 17.0 and Windows 7

Thanks a lot for your help in advance. Regards, Pablo
