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::
|
|
|
|
Quadrangle_2D_1 = Mesh_1.Quadrangle(algo=smesh.QUADRANGLE,geom=Face_1)
|
|
|
|
is replaced by::
|
|
|
|
Quadrangle_2D_1 = Mesh_1.Quadrangle(algo=smeshBuilder.QUADRANGLE,geom=Face_1)
|
|
|
|
StdMeshers algorithms concerned are *REGULAR, PYTHON, COMPOSITE, 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
