<p class="MsoNormal">You could use the Programmable Filter to create a new structured grid with the C+1 number of points in each dimension and then set the point data array in the C-sized grid to be a cell data array in the (C+1)-sized grid. The data layout
is such that that should work. However, you will need to set up the points manually.<o:p></o:p></p>
