Detailed Description
template<typename GV, int k, typename R = double>
class Dune::Functions::RefinedLagrangePreBasis< GV, k, R >
class Dune::Functions::RefinedLagrangePreBasis< GV, k, R >
A pre-basis for a refined Lagrange bases.
- Template Parameters
-
GV The grid view that the FE basis is defined on k The polynomial order of ansatz functions R Range field-type used for shape function values
- Note
- This only works for simplex grids.
Constructor & Destructor Documentation
◆ RefinedLagrangePreBasis()
template<typename GV , int k, typename R = double>
|
inline |
Constructor for a given grid view object.
- Parameters
-
gv The GridView the basis is defined on.
- Exceptions
-
Dune::NotImplemented If an element of type !simplex is found.
References DUNE_THROW, and Dune::FloatCmp::gt().
Member Function Documentation
◆ order()
template<typename GV , int k, typename R = double>
|
inlinestaticconstexpr |
Polynomial order used in the local Lagrange finite-elements.
- Note
- The local function is of order
k
only in subdomains of the element. It might be necessary to use a subdivided quadrature rule for integration.
