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


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)));


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
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;
