Detailed Description

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

     TConstBasisQuadBEMBF 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
