Detailed Description
class Dune::Functions::DefaultGlobalBasis< PB >
Global basis for given pre-basis.
This class implements the interface of a global basis using the details from a given pre-basis. Hence it serves as an example for this interface.
If you want to implement your own global basis, it may be better to implement a pre-basis instead. On the one hand this needs less boiler-plate code. On the other hand it makes your implementation composable and thus much more flexible. That is, you can reuse your pre-basis as one part in a larger product space by plugging it e.g. into a CompositePreBasis of PowerPreBasis. The actual global basis for your FooPreBasis is then obtained by using DefaultGlobalBasis<FooPreBasis>.
- Template Parameters
-
PB Pre-basis providing the implementation details
Constructor & Destructor Documentation
◆ DefaultGlobalBasis() [1/2]
|
inline |
Constructor.
- Template Parameters
-
T Argument list for PreBasis
- Parameters
-
t Argument list for PreBasis
This will forward all arguments to the constructor of PreBasis
◆ DefaultGlobalBasis() [2/2]
|
inline |
Constructor from a PreBasis factory.
- Parameters
-
gridView The GridView this basis is based on factory A factory functor that gets the gridView
and returns aPreBasis
Member Function Documentation
◆ update()
|
inline |
Update the stored grid view.
This will update the indexing information of the global basis. It must be called if the grid has changed.
