IntegrationPointValuesMethod

template<typename LocalAssemblerCollection >

using NumLib::ExtrapolatableLocalAssemblerCollection< LocalAssemblerCollection >::IntegrationPointValuesMethod

Initial value:

 
        std::function<std::vector<double> const&(
            LocalAssembler const& loc_asm, const double t,
            std::vector<GlobalVector*> const& x,
            std::vector<NumLib::LocalToGlobalIndexMap const*> const& dof_table,
            std::vector<double>& cache)>

A method providing integration point values of some property.

The method must return reference to a vector containing the integration point values.

For further information about the cache parameter see ExtrapolatableElementCollection::getIntegrationPointValues().

LocalAssembler

template<typename LocalAssemblerCollection >

using NumLib::ExtrapolatableLocalAssemblerCollection< LocalAssemblerCollection >::LocalAssembler

Initial value:

                                           [static_cast<std::size_t>(0)])>

LocalAssemblerCollection contains many LocalAssembler's.

template<typename LocalAssemblerCollection >

NumLib::ExtrapolatableLocalAssemblerCollection< LocalAssemblerCollection >::ExtrapolatableLocalAssemblerCollection ( LocalAssemblerCollection const & local_assemblers, IntegrationPointValuesMethod const & integration_point_values_method )

inline

Constructs a new instance.

Parameters

local_assemblers	a collection of local assemblers whose integration point values shall be extrapolated.
integration_point_values_method	a LocalAssembler method returning integration point values of some property for that local assembler.

getIntegrationPointValues()

template<typename LocalAssemblerCollection >

std::vector< double > const & NumLib::ExtrapolatableLocalAssemblerCollection< LocalAssemblerCollection >::getIntegrationPointValues ( std::size_t const id, const double t, std::vector< GlobalVector * > const & x, std::vector< NumLib::LocalToGlobalIndexMap const * > const & dof_table, std::vector< double > & cache ) const

inlineoverridevirtual

Returns integration point values of some property of a specific element.

Parameters

id	ID of the element of which the property is queried.
t	The time used in the evaluation if time dependent quantities.
x	The current solutions of a ProcessLib::Process; more generally any nodal GlobalVector pointers for each process.
dof_table	The processes d.o.f. table used to get each element's local d.o.f. from x.
cache	Can be used to compute a property on-the-fly.

Remarks

Since this method returns a reference, integration point values can not be computed locally and just returned.

Instead, the vector cache can be used to store some derived quantities that should be used as integration point values. They can be written to the cache and a reference to the cache can then be returned by the implementation of this method. Ordinary integration point values can be returned directly (if they are stored in the local assembler), and the cache can be left untouched.

For usage examples see the processes already implemented or the unit test in TestExtrapolation.cpp
