Dear all,
my triangulation is two-dimensional and consists of quadrilaterals, i.e. four vertices per cell. Each cell has four quadrature points (qp's). I visualize the data at the quadrature points (in paraview) by producing a discontinuous finite element field which has as many DoFs as my triangulation has qp's, that is, the qp values are somehow assigned to the nodes. In paraview (or other visualization programs) I would like to see four piecewice constant "colors" on every element: Sloppy speaking, each cell is divided into four subcells, and each of the subcells shows only one color which corresponds to the nodal value belonging to that subcell. To this end, I think I need a finite element with piecewise constant shape functions. Each shape function is '1' at one quarter of the reference domain and '0' at the remaining three quarters. Or is there an easier way to do this? If not, I probably would have to write my own finite element class, given that such an element does not exist in dealii?
