示例1: make_pair

const PRESS& pressure )
{
// pick an element
const std::size_t numElements = std::distance( mesh.elementsBegin(), mesh.elementsEnd() );
const std::size_t elemNum = (numElements +
static_cast<std::size_t>(std::sqrt(numElements)) ) / 2;
// geometry
const typename MESH::Element* geomEp = mesh.elementPtr( elemNum );
const typename base::Vector<MESH::Element::dim>::Type xi =
base::constantVector<MESH::Element::dim>( 0. );
const typename base::Geometry<typename MESH::Element>::result_type x =

// displacement
const typename DISP::Element* dispEp = displacement.elementPtr( elemNum );
const typename base::Vector<DISP::DegreeOfFreedom::size>::Type uh =
base::post::evaluateField( geomEp, dispEp, xi );
// pressure
const typename PRESS::Element* pressEp = pressure.elementPtr( elemNum );

double errorSquared = 0.;
