Detailed Description

Class to describe transformation of indices from one block to another.

Constructor & Destructor Documentation

◆ IndicesTransformation() [1/2]

IndicesTransformation::IndicesTransformation ( )

null constructor leaves object in undefined state.

◆ IndicesTransformation() [2/2]

IndicesTransformation::IndicesTransformation	(	const IntVect &	a_permutation,
		const IntVect &	a_sign,
		const IntVect &	a_translation
	)

Constructor.

IntVect pOld: indices of a cell in old index space IntVect pNew: indices of the same cell in new index space

Then for each direction idir: pNew[idir] = a_sign[idir]*pOld[a_permutation[idir]] + a_translation[idir].

◆ transformFwd() [1/3]

IntVect IndicesTransformation::transformFwd ( const IntVect & a_ivOld ) const

IntVect pOld: indices of a cell in old index space IntVect pNew: indices of the same cell in new index space

Then for each direction idir: pNew[idir] = m_sign[idir]*pOld[m_permutation[idir]] + m_translation[idir] and hence: pOld[m_permutation[idir]] = m_sign[idir]*pNew[idir]

m_sign[idir]*m_translation[idir]

	)		const

Transform coordinates in mapped space, not an index.

◆ transformVectorFwd()

IntVect IndicesTransformation::transformVectorFwd ( const IntVect & a_vecOld ) const
