◆ Resequence()

void TPZSloan::Resequence	(	TPZVec< int64_t > &	perm,
		TPZVec< int64_t > &	iperm
	)

virtual

int nen = 2; // number of nodes per element int *npn = new int[nen * n_elements]; // npn[i..i+nen] contains adjacent nodes of element i int *xnpn = new int[n_elements+1]; // xnpn[i] index of element i in npn

Now npn and xnpn are fElementGraph and fElementGraphIndex respectively
