Detailed Description

Fix class for UPML.

Work with this class assumes 3 stages:

1. Creation, setting pointer at the mesh for field E and time step dt.
2. Record of contours inside UPML, function record. Function record calls function put_media_coeffs (put_medium) of the mesh with parameters Ca and Cb, used in basuc update procedure E=Ca*E+Cb*rotH.
3. UPML update, functions step_bere and step after.

Pointer at the object emFixUPML and mesh E is hold by bdescr (objects of bdescr are collected by emBlockContainer). This object is initialized and recorded at the stage of contours analysis performed by emBlockContainer.

Member Function Documentation

record()

template<class block_t >

int emFixUPML::record	(	block_t *	block,
		const typename block_t::contour_it &	cnti,
		const Vector_3	sigma,
		const Vector_3	kappa,
		valtype	eps,
		valtype	mue,
		emtype &	Ca,
		emtype &	Cb
	)

Record data where UPML fix should be applied: contour iterator cnti (from the mesh block).

sigma and kappa are PML parameters, eps are mue parameters of the adjacent medium
