open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi community,

I am making a T2D model, based on GIS data which are in Lambert 93 (french projection). With this projection, the coordinate are like :

x : 500 000
y : 6 000 000.

I made a mesh with Blue Kenue from this data, and after i want to import it in fudaa in order to define the boundary conditions. But fudaa doesn't manage to open it and write the following error :

"grave : erreur lors de la génération de la frontière. L'indice 98 n'a pas de voisin.
Avertissement : Nombre d'éléments mal orientés : 9".

I already had this error in a previous project and i resolved it by moving all my data to the point 0,0(Origin). But i hope it is possible to use diectly lambert 93 coordinates in fudaa. Somebody on this forum already told me :

"If the coordinates are greater than one million, you must activate the "SERAFIND" option for file formats in the format "serafin". Fudaa can automatically read this format."

So i try to put in my .cas file the following line :

FORMAT DU FICHIER DE GEOMETRIE : SERAFIND

But it still doesn't work.

Any help will be appreciated.

Thanks

JP

Unfortunately, Blue Kenue doesn't yet create double precision selafin files so I presume that your current error comes from fudaa trying to read the (BK produced) single precision file as double precision.
