  • Meshing of two solid whose share a Face

    Hi,

    I want to mesh a composition of two solids : domain = MakeCompound([domain_1,domain_2]).
    Those two solids share a Face. I have to fix a boundary condition on this Face.
    What do I have to build whith GEOM Component for make a meshing of domain ?

    Thanks in advance,

    Thomas B.

      Hello,

       A small code, better that a long explain (perhaps !)
      from geompy import *

      import smesh

      # Géométrie
      # =========

      # 2 boites avec une face commune dont on veut la mettre dans un groupe afin d'y poser une condition limite.

      # Paramètres
      # ----------

      nom = "ex22_group"

      boite_x = 0
      boite_y = 0
      boite_z = 0

      cote = 60

      # Boites
      # ------

      delta = cote/2.0

      boite_1  = MakeBox(boite_x-delta, boite_y-delta, boite_z-delta,  boite_x+delta, boite_y+delta, boite_z+delta)

      boite_2  = MakeTranslation(boite_1, cote, 0, 0)

      # Pièce
      # -----

      cpd = MakeCompound([boite_1, boite_2])
      piece = MakeGlueFaces(cpd, 0.01)

      addToStudy(piece, nom)

      # Groupe de face
      # --------------

      cl = CreateGroup(piece, ShapeType["FACE"])

      cl_nom = nom + ":cl"
      addToStudy(cl, cl_nom)
      cl.SetName(cl_nom)

      face = GetFaceNearPoint(piece, MakeVertex(boite_x+delta, 0, 0))

      UnionList(cl, [face])

      # Maillage
      # ========

      # Définition du maillage
      # ----------------------

      tetra = smesh.Mesh(piece, nom)

      algo1d = tetra.Segment()
      algo1d.LocalLength(10)

      algo2d = tetra.Triangle()
      algo2d.LengthFromEdges()

      algo3d = tetra.Tetrahedron(smesh.NETGEN)
      algo3d.MaxElementVolume(100)

      tetra.Compute()

      # Groupe de maille pour la condition limite
      # -----------------------------------------

      tetra.Group(cl)
      # -------------------------

      You see in the study the mesh and a group of triangle based on the geometric common face.

        Thanks,
