Detailed Description

template<class Basis, class TP>
class AMDiS::PeriodicBC< Basis, TP >

Implements a periodic boundary condition.

Template Parameters

Mat	Matrix
Sol	Vector of solution
Rhs	Vector of rhs
Basis	RowBasis, must be the same as ColBasis
TP	Treepath to the node this constraint applies to

Member Function Documentation

apply()

void apply	(	Mat &	matrix,
		Sol &	solution,
		Rhs &	rhs
	)

Move matrix rows (and columns) of dependant DOFs to the corresponding master DOFs.

Add rows (and columns) of dependant DOFs to rows (and columns) master DOFs and set rows (and columns) of dependant DOFs to unit-rows[columns] with entries of -1 at master DOF indices. Uses a backend-specific implementation.

init()

void init

Compute the pairs of associated boundary DOFs.

After leaving the function the vector used by periodicNodes() is initialized and its value is true for all DOFs on the periodic boundary. Furthermode associations() is initialized and contains the index of the DOF associated to a DOF on the periodic boundary.
