Class xlifepp::FeSubSpace

class FeSubSpace : public xlifepp::SubSpace

Inheritence diagram for xlifepp::FeSubSpace:

Collaboration diagram for xlifepp::FeSubSpace:

inheriting from SubSpace handles additionnal data for elementary Fe type subspace.

Elementary means a subspace based on a single mesh domain (not an union of mesh domains) This structure is useful for Fe computation on sub domains, when the subdomain is not of the same dim as parent domain, Elements are SubElements

Public Functions

FeSubSpace(const GeomDomain&, Space&, bool, const string_t &na = "")

constructor specifying geom domain, parent subspace and name

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

constructor specifying geom domain, parent space and name

~FeSubSpace()

destructor

virtual void buildgelt2elt() const

construct the map get2elt from elements list

buildgelt2elt: construct the map gelt2elt from elements list and the map eltRanks thread safe because if not built, it is build only by the thread 0 other threads wait for the construction Note: it is better to build it outside a parallel region !

virtual const Element &element(GeomElement *gelt) const

access to element associated to a geomelement

inline virtual const Element &element(number_t k) const

access to k-th (k>=0) element (pointer) for FESpace and FESubspace only

virtual const Element *element_p(GeomElement *gelt) const

access to element associated to a geomelement

return element linked to a given geom element used gelt2elt map; has to be already built

inline virtual const Element *element_p(number_t k) const

access to k-th (k>=0) element (pointer) for FESpace and FESubspace only

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

access to dofs ranks (local numbering) of k-th (>=0) element for FESpace and FESubspace only

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

access to dofs ranks (parent numbering) of k-th (>=0) element for FESpace and FESubspace only

virtual const std::vector<FeDof> &feDofs() const

return fedofs vector

inline virtual const FeSubSpace *feSubSpace() const

autocast (see virtual function in parent)

template<typename T, typename K>
T &interpolate(const Vector<K>&, const Point&, const Element*, T&, DiffOpType = _id, bool useNearest = false) const

compute interpolated value at P knowing Element

template<typename T, typename K>
T &interpolate(const Vector<K>&, const Point&, T&, DiffOpType = _id, bool useNearest = false) const

compute interpolated value at P

inline virtual const Interpolation *interpolation() const

return pointer to interpolation

inline virtual bool isFeSubspace() const

returns true if FeSubSpace

const Element *locateElement(const Point &p, bool useNearest = false, bool errorOnDomainOut = true, real_t tol = theLocateToleranceFactor) const

locate element of the FeSubspace containing P

inline virtual number_t nbOfElements() const

number of elements for FESpace and FESubspace only

virtual number_t numElement(GeomElement *gelt) const

access to element number associated to a geomelement

inline virtual void print(PrintStream &os) const

print utility

virtual void print(std::ostream&) const

print utility

inline virtual const std::set<RefElement*> &refElements() const

access to set of pointer to RefElement (refElts) involved in FESpace

inline virtual Space *rootSpace()

access to root space pointer

inline virtual const Space *rootSpace() const

access to root space pointer (const)
