Detailed Description

Function Documentation

def GetSubMesh	(		self,
			geom,
			name
	)

Get a sub-mesh object associated to a geom geometrical object.

Parameters

geom	a geometrical object (shape)
name	a name for the sub-mesh in the Object Browser

Returns

an object of type SMESH.SMESH_subMesh, representing a part of mesh, which lies on the given shape

The sub-mesh object gives access to the IDs of nodes and elements. The sub-mesh object has the following methods:

• SMESH.SMESH_subMesh.GetNumberOfElements()
• SMESH.SMESH_subMesh.GetNumberOfNodes( all )
• SMESH.SMESH_subMesh.GetElementsId()
• SMESH.SMESH_subMesh.GetElementsByType( ElementType )
• SMESH.SMESH_subMesh.GetNodesId()
• SMESH.SMESH_subMesh.GetSubShape()
• SMESH.SMESH_subMesh.GetFather()
• SMESH.SMESH_subMesh.GetId()

  Note

  A sub-mesh is implicitly created when a sub-shape is specified at creating an algorithm, for example: algo1D = mesh.Segment(geom=Edge_1) creates a sub-mesh on Edge_1 and assign Wire Discretization algorithm to it. The created sub-mesh can be retrieved from the algorithm: submesh = algo1D.GetSubMesh()

def ClearSubMesh	(		self,
			geomId,
			refresh = False
	)

Remove all nodes and elements of indicated shape.

Parameters

refresh	if True, Object browser is automatically updated (when running in GUI)
geomId	the ID of a sub-shape to remove elements on

References Mesh.mesh.

def Compute	(		self,
			refresh = False
	)

Compute the sub-mesh and return the status of the computation.

Parameters

refresh

if True, Object browser is automatically updated (when running in GUI)

Returns

True or False

This is a method of SMESH.SMESH_submesh that can be obtained via Mesh.GetSubMesh() or Mesh_Algorithm.GetSubMesh().
