to force deal.ii to recognize that "cellData" should be interpreted as a
cell-based data. When I read the vtu files generated by this program via
ParaView, I found that although cellData looks like it is cell-based in the
visualization (i.e., it is discontinuous over the cells), the data array
itself is stored as a point array, so I couldn't use the
Cell_Data_to_Point_Data filter to get a smoothed and continuous visualization.
So, is there a way to write a cell-based data into cell arrays in vtu files?
No, all data produced by DataOut is point data. For cell-wise constants, it is
just written in a way that makes point data look piecewise constant.
You will have to find a different way to achieve what that filter does. What
does it do? Maybe we can suggest a way to achieve the same from within deal.II.
