◆ assemble()

template<uint8_t obs_num_dof, uint8_t src_num_dof>

template<typename OperatorType >

void bem::rwg::OperatorAssemblerBase< obs_num_dof, src_num_dof >::assemble	(	MatrixBase< Complex > &	mat,
		OperatorType	op,
		const Complex	k
	)

inline

Assembles the operator matrix for a given operator object and source and observation meshes.

Parameters

[out]	mat	- Matrix to store the assembled operator coefficients, with columns corresponding to source degrees of freedom, and rows corresponding to observation degrees of freedom.
[in]	op	- Operator object that computes the coefficients to be assembled into `mat`; must inherit from `OperatorBase<obs_num_dof, src_num_dof>`.
[in]	k	- Complex wavenumber.

Definition at line 115 of file base.hpp.

virtual void bem::rwg::OperatorAssemblerBase< obs_num_dof, src_num_dof >::prep_matrix ( MatrixBase< Complex > & mat )

pure virtual

Prepares the matrix for assembly (e.g., resizing and preallocation).

Parameters

[out] mat - Matrix to store the assembled operator coefficients, with columns corresponding to source degrees of freedom, and rows corresponding to observation degrees of freedom.

Implemented in bem::rwg::EdgeOperatorAssembler, bem::rwg::FaceOperatorAssembler, bem::rwg::FaceEdgeOperatorAssembler, bem::rwg::EdgeFaceOperatorAssembler, and bem::rwg::VectorOperatorsAssembler.
