Restriction

class dolfin.cpp.mesh.Restriction(*args)

Bases: object

This class represents a restriction of a mesh to a subdomain, which can be defined as a subset of all the cells, the facets, or possibly lower dimensional entities of the mesh.

Overloaded versions

• Restriction(mesh, sub_domain)

  Create cell-based restriction from subdomain

  Arguments

  mesh (Mesh)

  The mesh

  sub_domain (SubDomain)

  Sub domain defining the restriction

• Restriction(mesh, sub_domain, dim)

  Create restriction from subdomain to entities of arbitrary dimension

  Arguments

  mesh (Mesh)

  The mesh

  sub_domain (SubDomain)

  Sub domain defining the restriction

  dim (int)

  Dimension of restriction

• Restriction(domain_markers, domain_number)

  Create restriction from domain markers

  Arguments

  domain_markers (MeshFunction)

  Domain markers for the cells of the mesh.

  domain_number (int)

  Identifier for domain.

• Restriction(domain_markers, domain_number)

  Create restriction from domain markers (shared pointer version)

  Arguments

  domain_markers (MeshFunction)

  Domain markers for the cells of the mesh.

  domain_number (int)

  Identifier for domain.
