MultiMeshForm¶

class dolfin.cpp.fem.MultiMeshForm(*args)¶

Bases: object

This class represents a variational form on a cut and composite finite element function space (MultiMesh ) defined on one or more possibly intersecting meshes.

Create empty bilinear multimesh variational form.

Parameters:	const MultiMeshFunctionSpace > function_space_0 (std::shared_ptr<) – const MultiMeshFunctionSpace > function_space_1 (std::shared_ptr<) –

add()¶

Add form (shared pointer version)

Parameters:	const Form > form (std::shared_ptr<) – (`Form` ) The form.
Return type:	void

build()¶

Build MultiMesh form.

Return type:	void

clear()¶

Parameters:	i (std::size_t) – (std::size_t) Index
Return type:	std::shared_ptr< const MultiMeshFunctionSpace >
Returns:	`MultiMeshFunctionSpace` `Function` space shared pointer.

multimesh()¶

Extract common multimesh from form

Return type:	std::shared_ptr< const MultiMesh >
Returns:	`MultiMesh` The mesh.

multimesh_coefficient()¶

Get one multimesh coefficient.

Parameters:	i (std::size_t) –

num_parts()¶

Return the number of forms (parts) of the MultiMesh form

Return type:	std::size_t
Returns:	std::size_t The number of forms (parts) of the `MultiMesh` form.

part()¶

Return form (part) number i

Parameters:	i (std::size_t) –
Return type:	std::shared_ptr< const Form >
