NAME¶

test - test-function in variational formulation (rheolef-7.1)

DESCRIPTION¶

This class, and its associated trial one, is used for test and trial functions involved in variational formulations. Variational formulations are specified by expressions of the C++ language.

A test function is the formal argument involved in the expression for the integrate(3) function:

    geo omega ("circle");


    space Xh (omega, "P1");


    test v (Xh);


    field lh = integrate (omega, 2*v);

For a bilinear form(2), the test function represents its second formal argument, while its first one is referred to as the trial one:

    trial u (Xh);


    test  v (Xh);


    form a = integrate (omega, dot(grad(u),grad(v)));

IMPLEMENTATION¶

This documentation has been generated from file main/lib/test.h

The test and trial classes are simply aliases to the test_basic class:

typedef test_basic<Float,rheo_default_memory_model,details::vf_tag_01> test;
typedef test_basic<Float,rheo_default_memory_model,details::vf_tag_10> trial;

The test_basic class provides an interface, via the smart_pointer(7) class family, to a data container:

template <class T, class M, class VfTag>
class test_basic : public smart_pointer<test_rep<T,M> > {
public :
// typedefs:


    typedef test_rep<T,M>                    rep;


    typedef smart_pointer<rep>               base;


    typedef typename rep::size_type          size_type;


    typedef typename rep::memory_type        memory_type;


    typedef typename rep::value_type         value_type;


    typedef typename rep::scalar_type        scalar_type;


    typedef typename rep::float_type         float_type;


    typedef typename rep::geo_type           geo_type;


    typedef typename rep::space_type         space_type;


    typedef typename rep::diff_type          diff_type;


    typedef VfTag                            vf_tag_type;


    typedef typename details::dual_vf_tag<VfTag>::type


                                             vf_dual_tag_type;


    typedef test_basic<T,M,VfTag>            self_type;


    typedef test_basic<T,M,vf_dual_tag_type> dual_self_type;
// allocator/deallocator:


  


    explicit test_basic (const space_type& V) : base(new_macro(rep(V))) {}
// accessors:


    const space_type&  get_vf_space()  const { return base::data().get_vf_space(); }


    static const space_constant::valued_type valued_hint = rep::valued_hint;


    space_constant::valued_type valued_tag() const { return base::data().valued_tag(); }


    size_type n_derivative() const { return base::data().n_derivative(); }


    size_type size() const { return get_vf_space().size(); }


    details::test_component<T,M,VfTag> operator[] (size_type i_comp) const;
