ChangeToQuarterPoint()

TPZGeoEl * TPZChangeEl::ChangeToQuarterPoint ( TPZGeoMesh *  Mesh, int64_t  ElemIndex, int  targetSide  )

static

Slide middle nodes of an quadratic geoelement to the quarterpoint with respect to a given side.

Embora o elemento quadratico possua mais nohs (NNodes), a topologia segue igual ao elemento linear no qual o elemento quadratico foi baseado.

Isso quer dizer que Linear(Geom::NNodes) < Quadratic(Geom::NNodes), mas Linear(Geom::NSides) = Quadratic(Geom::NSides)

Com isso a numeracao dos nohs nos meios das arestas coincide com a numeracao dos lados unidimensionais do elemento.
