    Hi, guys!

    I am compiling the codes in VS 2005, an error poped out:

    User forgot to define frontier number xx.

    in MeshGmesh, Line 198.

    I find that OpenFlower "wants" xx.msh file starts with "$NOD", but my gmsh-2.3.0-Windows gives the file with

    $MeshFormat
    2 0 8
    $EndMeshFormat
    $PhysicalNames
    5
    102 ""
    103 ""
    104 ""
    105 ""
    106 ""
    $EndPhysicalNames
    $Nodes
    ...

    start.

    does the versions between gmesh and OpenFlower have sone dependence?

    Helps are very appreciated!

      Save the mesh in .msh V1.0 first of all.

      Secondly you must hand define all your frontiers(physical surfaces) in your FLW. This will look something like:

      Gmsh mesh{
      file xx.msh
      frontiers{
      surface 100 walls
      .
      .
      .
      .
      etc

      Hope this helps
