open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello everyone,

I'm trying to run a simulation but I get this error:

|Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
|
|Backtrace for this error:
|#0 0x7FBFFC64B777
|#1 0x7FBFFC64BD7E
|#2 0x7FBFFBD87D3F
|#3 0x69FF17 in elebd_
|#4 0x62B7A0 in inbief_
|#5 0x4C73E2 in telemac2d_
|#6 0x4FA861 in MAIN__ at homere_telemac2d.f:?
|Segmentation fault (core dumped)

I have already read some topics about this problem..
but I can't find the solution
I enclose the .cas, .slf, .cli file

please, some one can help me to figure out this problem?
Thanks so much

Cristina

Hello Cristina

We need either the geometry file or some extra explanations to understand what's going wrong with your case.

Hello Riadh,
Thanks so much for your reply,
I added the selafin file,is it enough?

Best regards,

Cristina

Hello Cristina
I geuss that your file is large, that's why it can not be attached, please send it using other mean. Send it using google for instance to my mail riadh.ata at edf dot fr

with my best regards

Hello Riadh,

I sent to your email the geometry file.

Thanks so much,

Cristina

Hello Cristina

If you add the new keyword CHECKING MESH =YES, Telemac will analyse the quality of the mesh. You will see that you have lots of improvements to do:
- You have 177 over-constrained elements (this is possible but not recommended)
- you have 375 nodes with only 2 neighbors

But all theses features do not explain the segmentation falt. I will investigate a bit more.

With my best regards

I got it !
as I suspected it is a problem of mesh. This is not a finite element mesh (see figure)
You need to repair this part of the mesh. I will add an exception in order to detect this kind of situation.
Other point, I see that you are working from the case Monai. this case is using finite volumes, if you want to use finte elements, you should start with another case.

With my best regards

Hello Riadh,

thanks so much for your help , I will fix the mesh and I will let you know.

Best regards,

Cristina

Thanks so much Riadh for your help...I fixed the mesh..now it works.

Best regards,

Cristina

Hi..By using 2017 NCEP data ,landuse&landcover and land surface parameters I have put one simulation sir . That time I have got outputs . Now I am trying to put another simulation with 2016 NCEP data, while running wrf "segmentation fault occurs ".
