[Gmsh] Maillage couche limite

[pierre.dulieu at gdfsuez.com]

Bonjour,

J'aimerais mailler une couche limite en gmsh dans un maillage non structuré.
Je commence par un exemple basique d'un cube dans lequel je veux faire une couche limite sur une des faces (voir input ci-dessous).
Le raffinement tangentiel à la face se produit bien, mais pas le raffinement normal que j'impose à 0.02.
Pourriez-vous m'indiquer ce qui n'est pas correct dans cet exercice ?

Merci,
