Problem in running the 2D examples included in the package

Postby bproenca on Tue Feb 10, 2009 4:32 am

Hello Patrick,

I am learning how to use pCOULWAVE and I have been trying to run the examples that come with the 2008 version of the model.

I had no problems in running the 1D examples, but when I moved to the 2D ones I couldn't run them with your pre-established simulation setup, I would always get a segmentation fault message.

Then I tried to change a few parameters and the 2D_irregular_waves_real_beach example for instance, would only run if I set the Number of grid points per wavelength from 50 to 6, which is woefully low.

Could you please tell me what is going wrong.

Thank you

Best regards

Bárbara

Hi Bárbara

The error that you are getting, stack overflow, is due to your memory stack being set to a value that is too small for the code. If you are using Visual Fortran in Windows, you can change the stack size through:

Project>Settings>Link>Output

and put a value of

100000000

in both the Reserve and Commit boxes.

If you are using Linux, you need to set

stack unlimited

and you may also need to

export MPI_MAX_TYPE=1000000

Hello Patrick
I am learning how to use pCOULWAVE to do graduate thesis and I have been trying to run the examples that come with the 2008 version of the model,too.
I have problem in running the 2D examples,too.I put a value of 100000000 in both the Reserve and Commit boxes but still see to notify error
