MultiMeshAssembler

class dolfin.cpp.fem.MultiMeshAssembler

Bases: dolfin.cpp.fem.AssemblerBase

This class implements functionality for finite element assembly over cut and composite finite element (MultiMesh ) function spaces.

Constructor.

assemble()

Assemble tensor from given form

Parameters:

• & A (GenericTensor) – (GenericTensor ) The tensor to assemble.
• MultiMeshForm & a (const) – (Form ) The form to assemble the tensor from.

Return type:

void

extend_cut_cell_integration

extend_cut_cell_integration (bool) Default value is false. This controls whether the integration over cut cells should extend to the part of cut cells covered by cells from higher ranked meshes - thus including both the cut cell part and the overlap part.

Return type:bool
