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()
| TQuadBEMBF | ( | 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
◆ eval()
|
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
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 >.
◆ eval_kernel()
|
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
Implemented in THelmholtzDLPBF< T_ansatzsp, T_testsp >, TLaplaceDLPBF< T_ansatzsp, T_testsp >, THelmholtzSLPBF< T_ansatzsp, T_testsp >, TLaplaceSLPBF< T_ansatzsp, T_testsp >, and TAcousticScatterBF< T_ansatzsp, T_testsp >.
◆ reorder_common()
|
protected |
reorder triangle vertices such that the k common vertices are ordered from 0,…,k-1; the number of common vertices is returned
