open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear all,

I compiled the telemac v7p3r0 with additional source codes for a separate module which is coupled with telemac2d. The compilation is completed. However, i get some warning during the compilation which says "

ar: `u' modifier ignored since `D' is the default (see `U')
- completed: .../v7p3r1/builds/gfortran/lib/utils/special/special4stbtel.a


Such warning are received for all the modules.

After the compilation, when I try to run the t2d simulation coupled with that new module, I got the error which says, "

ITERATION 0 TIME: 0.0000 S
TOO MANY POINTS IN BANK PROFILE. WILL BE SIMPLIFIED.

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

When I don't couple that additional module, the simulation runs fine. So this couldn't be the problem of mesh.

The config file as well as the error snapshots are attached.

Any suggestions on how to get rid of this error?

Thank you

Hi
for the config file, I'm not sure about the two INCS_ALL lines. Maybe you should merge them
Nevertheless, according to the error message, I think the problem is located in your sources.
Looks like the segmentation faults occur in meandre...
Maybe you should try to run it in debug mode to see which index in which array generate this problem

For us, without your sources, it will be difficult to say more

Regards

Dear Christophe,

I have no idea on how to run in a debug mode. Is it possible to run in a debug mode even if i compiled only in scalar mode?

This source code (meandre) is a collaboration between EDF and USDA, which I received from EDF team.

If it is ok to share with you, I can. But my main problem is the time limit. I have a deadline to meet based on the simulation results of this module within next two weeks.

Thank you.

It could be more logical if it will be EDF which helps you...
look into the all config file to find a debug config and add one to your config. It's mainly just a compiler option.
Then once the debug version compiled, you could run it in the same way.

But when it crash, you will have more informations and also you will have the possibility to launch again the program inside the temporary directory with tools like GDB and execute the code line by line...

Regards
