Detailed Description

template<typename T_ansatzsp, typename T_testsp, typename T_val>
class HLIB::TInvarBasisQuadBEMBF< T_ansatzsp, T_testsp, T_val >

TConstBasusQuadBEMBF extends TQuadBEMBF for function spaces with invariant basis functions, e.g. with respect to translation, scaling and rotation. This allows their precomputation for the unit triangle, improving efficiency.

Constructor & Destructor Documentation

◆ TInvarBasisQuadBEMBF()

TInvarBasisQuadBEMBF ( const ansatzsp_t *  ansatzsp,
const testsp_t *  testsp,
const uint  order = CFG::BEM::quad_order,
const bool  dist_ada = CFG::BEM::adaptive_quad_order 
)

construct bilinear form over function spaces ansatzsp and testsp using quadratur with order order; if dist_ada is true, the quadrature order is adaptively adjusted according to distance

Member Function Documentation

◆ ansatz_val()

const std::vector< ansatz_value_t >* ansatz_val ( const idx_t  idx,
const TGrid::triangle_t tri,
const uint  ncommon,
const uint  order 
) const
inlineprotected

return ansatz basis function values for index idx in triangle tri for quadrature points with ncommon common vertices and order order

◆ eval()

virtual void eval ( const std::vector< idx_t > &  row_ind,
const std::vector< idx_t > &  col_ind,
BLAS::Matrix< value_t > &  values 
) const
virtual

evaluate subblock defined by row_ind × col_ind; the indices in row_ind and col_ind can be arbitrary, e.g. must not be contiguous

Reimplemented from TQuadBEMBF< T_ansatzsp, T_testsp, T_val >.

◆ test_val()

const std::vector< test_value_t >* test_val ( const idx_t  idx,
const TGrid::triangle_t tri,
const uint  ncommon,
const uint  order 
) const
inlineprotected
