Detailed Description

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

TQuadBEMBF extends TBEMBF by providing quadrature rules for triangle pairs and defining a kernel function evaluation interface.

Constructor & Destructor Documentation

TQuadBEMBF ( const ansatzsp_t *  ansatzsp,
const testsp_t *  testsp,
const uint  order,
const bool  dist_ada = false 

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

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

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

Implements TBilinearForm< T_val >.

Reimplemented in TInvarBasisQuadBEMBF< T_ansatzsp, T_testsp, T_val >, TInvarBasisQuadBEMBF< T_ansatzsp, T_testsp, real >, and TInvarBasisQuadBEMBF< T_ansatzsp, T_testsp, complex >.

const TGrid::triangle_t tri0,

std::vector< value_t > &  values 
) const
protectedpure virtual

compute kernel at quadrature points in triangles tri0idx and tri1idx with coordinate indices tri0 and tri1 using quadrature rule quad_rule; the results for all points are returned in values

uint reorder_common ( idx_t *  vtx0idxs,
idx_t *  vtx1idxs 
) const

reorder triangle vertices such that the k common vertices are ordered from 0,…,k-1; the number of common vertices is returned
