Documentation for SALOME %Mesh module Python API is available in two forms:
- <a href="smeshpy_doc/modules.html">Structured documentation</a>, where all methods and
-classes are grouped by their functionality, like it is done in the GUI documentation
+classes are grouped by their functionality.
- <a href="smeshpy_doc/namespaces.html">Linear documentation</a> grouped only by classes, declared
-in the \ref smesh and StdMeshersDC Python packages.
+in the \ref smeshBuilder and \ref StdMeshersBuilder Python packages.
-Python package \ref smesh provides an interface to create and handle
+\n With SALOME 7.2, the Python interface for %Mesh has been slightly modified to offer new functionality.
+\n You may have to modify your scripts generated with SALOME 6 or older versions.
+\n Please see \ref smesh_migration_page.
+
+Class \ref smeshBuilder.smeshBuilder "smeshBuilder" provides an interface to create and handle
meshes. It can be used to create an empty mesh or to import mesh from the data file.
As soon as mesh is created, it is possible to manage it via its own
-methods, described in \ref smesh.Mesh "class Mesh" documentation.
-
-Class \ref smesh.Mesh "Mesh" allows assigning algorithms to a mesh.
-Please note that some algorithms, included in the standard SALOME
-distribution are always available. Python package \ref StdMeshersDC
-provides an interface for standard meshing algorithms included into
-the SALOME %Mesh module distribution, like:
-- REGULAR (1D)
-- COMPOSITE (1D)
-- MEFISTO (2D)
-- Quadrangle (2D)
-- Hexa(3D)
-- etc ...
-
-To add meshing hypotheses, it is possible to use the functions provided by the
-algorithms interfaces.
+methods, described in class \ref smeshBuilder.Mesh "Mesh" documentation.
+
+Class \ref smeshstudytools.SMeshStudyTools "SMeshStudyTools" provides several methods to manipulate mesh objects in Salome study.
+
+A usual workflow to generate a mesh on geometry is following:
+<ol>
+ <li>Create an instance of \ref smeshBuilder.smeshBuilder "smeshBuilder":
+ <pre>
+ from salome.smesh import smeshBuilder
+ smesh = smeshBuilder.New( salome.myStudy )
+ </pre></li>
+ <li>Create a \ref smeshBuilder.Mesh "mesh" object:
+ <pre>
+ mesh = \ref smeshBuilder.smeshBuilder.Mesh "smesh.Mesh( geometry )"
+ </pre></li>
+ <li> Create and assign \ref basic_meshing_algos_page "algorithms" by
+ calling corresponding methods of the mesh. If a sub-shape is
+ provided as an argument, a \ref constructing_submeshes_page "sub-mesh"
+ is implicitly created on this sub-shape:
+ <pre>
+ regular1D = \ref smeshBuilder.Mesh.Segment "mesh.Segment"()
+ mefisto = \ref smeshBuilder.Mesh.Triangle "mesh.Triangle"( smeshBuilder.MEFISTO )
+ # use other triangle algorithm on a face -- a sub-mesh appears in the mesh
+ netgen = \ref smeshBuilder.Mesh.Triangle "mesh.Triangle"( smeshBuilder.NETGEN_1D2D, face )
+ </pre></li>
+ <li> Create and assign \ref about_hypo_page "hypotheses" by calling
+ corresponding methods of algorithms:
+ <pre>
+ segLen10 = \ref StdMeshersBuilder.StdMeshersBuilder_Segment.LocalLength "regular1D.LocalLength"( 10. )
+ maxArea = \ref StdMeshersBuilder.StdMeshersBuilder_Segment.LocalLength "mefisto.MaxElementArea"( 100. )
+ netgen.SetMaxSize( 20. )
+ netgen.SetFineness( smeshBuilder.VeryCoarse )
+ </pre>
+ </li>
+ <li> \ref compute_anchor "Compute" the mesh (generate mesh nodes and elements):
+ <pre>
+ \ref Mesh.Compute "mesh.Compute"()
+ </pre>
+ </li>
+</ol>
+
+An easiest way to start with Python scripting is to do something in
+GUI and then to get a corresponding Python script via
+<b> File > Dump Study </b> menu item. Don't forget that you can get
+all methods of any object in hand (e.g. a mesh group or a hypothesis)
+by calling \a dir() Python built-in function.
+
+All methods of the Mesh Group can be found in \ref tui_create_standalone_group sample script.
An example below demonstrates usage of the Python API for 3d mesh generation.
