Bonjour,
votre fichier exp.geo est correct.
Ce n'est pas nous qui avons écrit le programme gmshToFoam , vous devriez vous
renseigner directement chez OpenFoam...
Concernant les couches limites, vous pouvez essayer
http://www.geuz.org/gmsh/doc/texinfo/gmsh-full.html#SEC45
Extrude { Surface { expression-list }; layers }
Extrudes a boundary layer along the normals of the specified surfaces.
J'attache des exemples.
Cordialement,
Dave

bonjour,
je suis une utilisatrice récente du logiciel gmsh en vue de générer un
maillage destinée à un usage sous OpenFoam. lors de la conversion du
file.msh avec gmshToFoam j'ai rencontré quelques problèmes. pouvez vous
m'aider!?
je joint l'exemple que j'ai essayé de tourner qu iest vraiment basique
avec les erreurs générées par la commande gmshToFoam.
dans un autre registre, je me demandais commant on pouvait mailler des
couches limites avec gmsh.
en vous remerciant d'avance,
cordialement,
