-Modifying Mesh Python scripts from SALOME 6 and before
-******************************************************
-
-In SALOME 7.2, the Python interface for Mesh has been slightly modified to offer new functionality:
-
-
-Scripts generated for SALOME 6 and older versions must be adapted to work in SALOME 7.2 with full functionality.
-The compatibility mode allows old scripts to work in almost all cases, but with a warning.
-
-See also *"Modifying Geometry Python scripts from SALOME 6 and before"* page in the Geometry module's
-User Guide.
-
-* **Salome initialisation** must always be done as shown below.
-
- (*salome_init()* can be invoked safely several times)::
-
- import salome
- salome.salome_init()
-
-* **smesh initialisation** is modified.
-
- The old mode (from dump)::
-
- import smesh, SMESH, SALOMEDS
- smesh.SetCurrentStudy(salome.myStudy)
-
- The new mode::
-
- import SMESH, SALOMEDS
- from salome.smesh import smeshBuilder
- smesh = smeshBuilder.New()
-
-
-* Of course, **from smesh import** * is **no more possible.**
-
- You have to explicitly write *smesh.some_method()*.
-
-* All **algorithms** have been transferred from the namespace *smesh* to the namespace *smeshBuilder*.
-
- For instance::
-
- MEFISTO_2D_1 = Mesh_1.Triangle(algo=smesh.MEFISTO,geom=Face_1)
-
- is replaced by::
-
- MEFISTO_2D_1 = Mesh_1.Triangle(algo=smeshBuilder.MEFISTO,geom=Face_1)
-
- StdMeshers algorithms concerned are *REGULAR, PYTHON, COMPOSITE, MEFISTO, Hexa, QUADRANGLE, RADIAL_QUAD*.
-
- SMESH Plugins provide such algorithms as: *NETGEN, NETGEN_FULL, FULL_NETGEN, NETGEN_1D2D3D, NETGEN_1D2D, NETGEN_2D, NETGEN_3D*.
-
- If you use DISTENE plugins, you also have *BLSURF, GHS3D, GHS3DPRL, Hexotic*.
-
-* Some **variables** were available in both namespaces *smesh* and *SMESH*. Now they are available only in namespace *SMESH*.
-
- The dump function used only the namespace *SMESH*,
- 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:
-
- * *NODE, EDGE, FACE, VOLUME, ALL.*
- * *FT_xxx, geom_xxx, ADD_xxx...*
-
- For instance::
-
- 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)
-
- is replaced by::
-
- 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)
-
-
-* The namespace **smesh.smesh** does not exist any more, use **smesh** instead.
-
- For instance::
-
- Compound1 = smesh.smesh.Concatenate([Mesh_inf.GetMesh(), Mesh_sup.GetMesh()], 0, 1, 1e-05)
-
- is replaced by::
-
- Compound1 = smesh.Concatenate([Mesh_inf.GetMesh(), Mesh_sup.GetMesh()], 0, 1, 1e-05)
-
-* If you need to **import a SMESH Plugin** explicitly, keep in mind that they are now located in separate namespaces.
-
- For instance::
-
- import StdMeshers
- import NETGENPlugin
- import BLSURFPlugin
- import GHS3DPlugin
- import HexoticPLUGIN
-
- is replaced by::
-
- from salome.StdMeshers import StdMeshersBuilder
- from salome.NETGENPlugin import NETGENPluginBuilder
- from salome.BLSURFPlugin import BLSURFPluginBuilder
- from salome.GHS3DPlugin import GHS3DPluginBuilder
- from salome.HexoticPLUGIN import HexoticPLUGINBuilder
