open TELEMAC-MASCARET The mathematically superior suite of solvers

hello

Thank you very much for your help ! It works in several case but I have a new problem with a new project. It is working well when I launch simulations without wave breaking. When I try to launch it with breakin it crashes with "pivot nul à la ligne xxx". Is it a way to fix it ?

thanks a lot

Hi,

Here my artemis files.

Hello,

=> Romain_D,
Do you have the same problem as Tannycke?
I tested your case this morning and the calculation do not lead to a "pivot nul" in my V6P0... Can you send your error message?

=> Tannycke,
Can you send your files for me to test it.

Regards,

Christophe

hello

the file is too big to put it on the forum, consequently you coulf find it on this link :

Thanks a lot for your help !

Hello Christophe,

Thanks to your help.

I have the same error as tannycke:


PERIODE 1/ 2 : 6.5127 SECONDES


DIRECTION 1/ 2 : 263.1112 DEGRES

PHBOR : IL Y A : 1 FRONTIERE(S) DE TYPE ONDE INCIDENTE

RESOLUTION DU SYSTEME LINEAIRE (SOLVE)

RESOLUTION DIRECTE

PLANTE : ARRET DU PROGRAMME APRES ERREUR

And I do not find yet the solution! I tested some .cas which worked on v5p9, but it did not work with v6p0.

Regards.

Hi,

I found another way to perform my artemis model. We have a old version of telemac (V5P9), so I ran my model with V5P9 and it works.

However if you found a solution for V6P0 I'm still interested.

Best Regards

Hello,

The problem of very slightly negative values that cause formulas such as X**2.D0 to crash has been solved in version 6.1 by putting X**2 which is the correct and efficient way of squaring, but there is still a difference with older versions that has not been explained. We still work on this.

Hello,
I had a look at your user routine borh.f. You have to use
LIHBORT(I) instead of LIHBOR%I(I). they aren't the same work array (an error) in V6P0.
I think, error comes from tehre
