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	(	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

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

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
