Class xlifepp::SubSpace

class SubSpace : public xlifepp::Space

Inheritence diagram for xlifepp::SubSpace:

Collaboration diagram for xlifepp::SubSpace:

defines data related to a ‘subspace’ of a space the subspace may be geometrically supported by a subset of geometrical domain or be a restriction to a boundary of the parent geometrical domain (trace space) or both The SubSpace class is mainly used as a dof numbering object in computation.

SubSpace class is not exposed to end users

Subclassed by xlifepp::FeSubSpace

Public Functions

inline SubSpace()

default constructor

SubSpace(const GeomDomain&, const std::vector<number_t>&, Space&, const string_t &na = "")

constructor specifying geom domain, dof ids list and parent space and name

SubSpace(const GeomDomain&, Space&, const string_t &na = "")

constructor specifying geom domain, parent space and name

SubSpace(const std::vector<number_t>&, Space&, const string_t &na = "")

constructor specifying dof ids list and parent space and name

~SubSpace()

destructor

virtual void builddofid2rank() const

construct the map dofid2rank from dofNumbers list

construct the map dofid2rank from dofs list, ranks start from 1

void createNumbering()

create numbering of subspace DoFs

inline virtual number_t dimSpace() const

dim of subspace (number of DoFs)

inline virtual const Dof &dof(number_t n) const

return n-th fedof as dof (n=1,…)

inline virtual number_t dofId(number_t n) const

return the DoF id of n-th space DoF (n=1,…)

inline virtual const std::map<number_t, number_t> &dofid2rank() const

return the map dof to rank, built on fly

virtual std::vector<number_t> dofIds() const

return the DoF ids on subspace

inline std::vector<number_t> &dofNumbers()

access to dofNumbers list

inline const std::vector<number_t> &dofNumbers() const

access to dofNumbers list (const)

number_t dofRootNumber(number_t k) const

access to dof number in root space numbering

std::vector<number_t> dofRootNumbers() const

access to dofNumbers list in root space numbering

access to dofNumbers list in root space numbering remind that dofNumbers vector in SubSpace is related to the numbering of parent which can be a subspace and not the root space

void dofsOfFeSubspace()

build dofs numbering of Fe SubSpace

build dofs numbering of subspace when parent is a Fe space if domain is a composite domain (union or intersection of domains)

• subspaces of each domain are created if they do not exist

• dofNumbers numbering relative to parent space is computed if domain is a meshdomain, dofNumbers is computed by function

void dofsOfSpSubspace()

build dofs numbering of Sp SubSpace

void dofsOfSubSubspace()

build dofs numbering of Subspace of SubSpace

build dofs numbering of subspace when parent is a Subspace two cases are possible:

• domain is a meshdomain and domain parent is a composite domain (e.g D1 and D1+D2)

• domain and parent domains are composite domains (e. g D1+D2 and D1+D2+D3) we use a general algorithm based on root dof numbers comparison

inline virtual const Element *element_p(number_t k) const

inline virtual const std::vector<number_t> &elementDofs(number_t k) const

inline virtual std::vector<number_t> elementParentDofs(number_t k) const

virtual bool isFE() const

true if FE space or FeSubspace

inline virtual bool isFeSubspace() const

returns false (a subspace is not a fesubspace)
