/*! \page smesh_migration_page Modifing Mesh Python scripts from SALOME 6 and before \n In SALOME 7.2, the Python interface for %Mesh has been slightly modified to offer new functionality: <ul> <li>\subpage tui_execution_distribution_page</li> <li>\subpage tui_auto_completion_documentation_page</li> </ul> \n Scripts generated for SALOME 6 and older versions must be adapted to work in SALOME 7.2 with full functionality. \n The compatibility mode allows old scripts to work in almost all cases, but with a warning. See also \subpage geompy_migration_page <b>Salome initialisation must always be done as shown below</b> \n (<em>salome_init()</em> can be invoked safely several times): \code import salome salome.salome_init() \endcode <b>smesh initialisation is modified.</b> \n the old mode (from dump): \code import smesh, SMESH, SALOMEDS smesh.SetCurrentStudy(theStudy) \endcode \n the new mode: \code import SMESH, SALOMEDS from salome.smesh import smeshBuilder smesh = smeshBuilder.New(salome.myStudy) \endcode <b> Of course, <em>from smesh import *</em> is no more possible.</b> \n You have to explicitely write <em>smesh.some_method()</em>. <b>All algorithms have been transferred from the namespace <em>smesh</em> to the namespace <em>smeshBuilder</em>.</b> \n For instance: \code MEFISTO_2D_1 = Mesh_1.Triangle(algo=smesh.MEFISTO,geom=Face_1) \endcode is replaced by: \code MEFISTO_2D_1 = Mesh_1.Triangle(algo=smeshBuilder.MEFISTO,geom=Face_1) \endcode \n StdMeshers algoritms concerned are <em>REGULAR, PYTHON, COMPOSITE, MEFISTO, Hexa, QUADRANGLE, RADIAL_QUAD</em>. \n SMESH Plugins provide such algorithms as: <em> NETGEN, NETGEN_FULL, FULL_NETGEN, NETGEN_1D2D3D, NETGEN_1D2D, NETGEN_2D, NETGEN_3D</em>. \n If you use DISTENE plugins, you also have <em>BLSURF, GHS3D, GHS3DPRL, Hexotic</em>. <b>Some variables were available in both namespaces <em>smesh</em> and <em>SMESH</em>. Now they are available only in namespace <em>SMESH</em></b>. \n The dump function used only the namespace <em>SMESH</em>, so, if your script was built with the help of the dump function, it should be already OK in this respect. The most used variables concerned are: \n <em>NODE, EDGE, FACE, VOLUME, ALL.</em> \n <em>FT_xxx, geom_xxx, ADD_xxx...</em> \n For instance: \code srcFaceGroup = srcMesh.GroupOnGeom( midFace0, "src faces", smesh.FACE ) mesh.MakeGroup("Tetras",smesh.VOLUME,smesh.FT_ElemGeomType,"=",smesh.Geom_TETRA) filter = smesh.GetFilter(smesh.FACE, smesh.FT_AspectRatio, smesh.FT_MoreThan, 6.5) \endcode is replaced by: \code srcFaceGroup = srcMesh.GroupOnGeom( midFace0, "src faces", SMESH.FACE ) mesh.MakeGroup("Tetras",SMESH.VOLUME,SMESH.FT_ElemGeomType,"=",SMESH.Geom_TETRA) filter = smesh.GetFilter(SMESH.FACE, SMESH.FT_AspectRatio, SMESH.FT_MoreThan, 6.5) \endcode <b>The namespace <em>smesh.smesh</em> does not exist any more, use <em>smesh</em> instead.</b> \n For instance: \code Compound1 = smesh.smesh.Concatenate([Mesh_inf.GetMesh(), Mesh_sup.GetMesh()], 0, 1, 1e-05) \endcode is replaced by: \code Compound1 = smesh.Concatenate([Mesh_inf.GetMesh(), Mesh_sup.GetMesh()], 0, 1, 1e-05) \endcode <b>If you need to import a %SMESH Plugin explicitely, keep in mind that they are now located in separate namespaces.</b> \n For instance: \code import StdMeshers import NETGENPlugin import BLSURFPlugin import GHS3DPlugin import HexoticPLUGIN \endcode is replaced by: \code from salome.StdMeshers import StdMeshersBuilder from salome.NETGENPlugin import NETGENPluginBuilder from salome.BLSURFPlugin import BLSURFPluginBuilder from salomeGHS3DPlugin .import GHS3DPluginBuilder from salome.HexoticPLUGIN import HexoticPLUGINBuilder \endcode */
