Pre-basis for lowest order Taylor-Hood basis. More...

#include <dune/functions/functionspacebases/taylorhoodbasis.hh>

Public Types

using GridView = GV
 The grid view that the FE basis is defined on.
 
using size_type = std::size_t
 Type used for indices and size information.
 
using Node = TaylorHoodBasisTree< GV >
 Template mapping root tree path to type of created tree node.
 

Public Member Functions

 TaylorHoodPreBasis (const GridView &gv)
 Constructor for a given grid view object.
 
void initializeIndices ()
 Initialize the global indices.
 
const GridViewgridView () const
 Obtain the grid view that the basis is defined on.
 
void update (const GridView &gv)
 Update the stored grid view, to be called if the grid has changed.
 
Node makeNode () const
 Create tree node.
 
size_type size () const
 Same as size(prefix) with empty prefix.
 
template<class SizePrefix >
size_type size (const SizePrefix &prefix) const
 Return number of possible values for next position in multi index.
 
size_type dimension () const
 Get the total dimension of the space spanned by this basis.
 
size_type maxNodeSize () const
 Get the maximal number of DOFs associated to node for any element.
 
auto containerDescriptor () const
 Return an container descriptor depending on the flag HI. Either return a Tuple if hybrid indices should be used, otherwise return an Array.
 

Detailed Description

template<typename GV, bool HI = false>
class Dune::Functions::TaylorHoodPreBasis< GV, HI >

Pre-basis for lowest order Taylor-Hood basis.

Template Parameters
GVThe grid view that the FE basis is defined on
HIFlag to select hybrid indices
Note
This mainly serves as an example, since you can construct a pre-basis with the same functionality manually using
static const int k = 1;
using VelocityPreBasis = PowerPreBasis<IMS,LagrangePreBasis<GV,k+1>,dim>;
using PressurePreBasis = LagrangePreBasis<GV,k>;
A pre-basis for composite bases.
Definition: compositebasis.hh:57
A pre-basis for a PQ-lagrange bases with given order.
Definition: lagrangebasis.hh:61
A pre-basis for power bases.
Definition: powerbasis.hh:52
Where IMS is BlockedInterleaved if HI is set and FlatInterleaved otherwise.
