[Gmsh] Epaisseur de paroi et maillage (message in english and french)

Wed Nov 23 14:56:03 CET 2005

Bonjour à tous.

Lorsque j'utilise ce fichier, le maillage ne marche pas en dessous d'une certaine épaisseur de paroi :

*       Si e=0.02 et e2=0.015, le maillage marche très bien

*       Si e=0.002 et e2=0.0015, GMSH plante et se ferme.

Quelqu'un peut-il m'expliquer ?

Merci d'avance. Cordialement,

Hi all.

When I use this geometry, I'm unable to mesh the volume with some parameter values:

*       With e=0.02 and e2=0.015, everything is ok

*       With e=0.002 and e2=0.0015, GMSH crash and close itself.

Can anybody explain that to me?

Thank you by advance. Best regards,
