Example
*******
The creation of the object case_1 is done as follows:

::

    case_name = "CAS_1"
    mesh_name = "MAILL"
    mesh_file = "/scratch/Salome/Adapt/m0.med"
    case_1 = homard.CreateCase(case_name, mesh_name, mesh_file)
    dirname = "/scratch/Salome/Adapt/resu"
    case_1.SetDirName(dirname)
    case_1.SetConfType(1)
    case_1.AddBoundaryGroup( 'intersection', '' )
    case_1.AddBoundaryGroup( 'cyl_1', 'T1_EXT' )
    case_1.AddBoundaryGroup( 'cyl_1', 'T2_EXT' )
    case_1.AddBoundaryGroup( 'cyl_2', 'T_INT' )
