[Gmsh] Décomposition d'un solide en deux entités - problème de maillage (French + english message)

Wed Nov 23 14:26:53 CET 2005

Bonjour à tous / hi all.

J'ai une question à propos de la décomposition de solides en différentes entités. Chacune des deux entités que j'ai défini peut être maillée séparémment, mais ensemble beaucoup de messages d'erreurs apparaissent et il n'y a pas de maillage.

Quelle commande me manque-t'il ?

Merci d'avance pour votre patience.

Voici le contenu du fichier .geo :

I have a question about decomposition of several physical entities. Each physical entity in my example can be easily meshed without the other part, but I can't mesh these two entities together.

What command line is missing, please ?

Thanks by advance for your help. I included the content of the .geo file:
