Function Documentation

set_periodicity_constraints()

template<typename FaceIterator , typename number >

void DoFTools::internal::set_periodicity_constraints	(	const FaceIterator &	face_1,
		const std_cxx20::type_identity_t< FaceIterator > &	face_2,
		const FullMatrix< double > &	transformation,
		AffineConstraints< number > &	affine_constraints,
		const ComponentMask &	component_mask,
		const unsigned char	combined_orientation,
		const number	periodicity_factor,
		const unsigned int	level = numbers::invalid_unsigned_int
	)

This function is internally used in make_periodicity_constraints(). Enter constraints for periodicity into the given AffineConstraints object.

This function works both on 1) an active mesh (level == numbers::invalid_unsigned_int) and on 2) multigrid levels.

In the case of an active mesh, this function is called when at least one of the two face iterators corresponds to an active object without further children. Furthermore, face_1 is supposed to be active.

The matrix transformation maps degrees of freedom from one face to another. If the DoFs on the two faces are supposed to match exactly, then the matrix so provided will be the identity matrix. if face 2 is once refined from face 1, then the matrix needs to be the interpolation matrix from a face to this particular child

Note

We have to be careful not to accidentally create constraint cycles when adding periodic constraints: For example, as the corresponding testcase bits/periodicity_05 demonstrates, we can occasionally get into trouble if we already have the constraint x1 == x2 and want to insert x2 == x1. We avoid this by skipping such "identity constraints" if the opposite constraint already exists.
