I'm not quite sure I understand the question. Are you seeing
problems<br>
when refining the grid using ALU's standard globalRefine method or
do the problems<br>
only appear when you use your local parametrization and after moving
nodes around<br>
(I'm not quite clear how you do that with ALU....).<br>

Therefore I compute the cell divergence summing over the cell

normal . flux * area<br>
where intersection normals and areas are computed by Dune
methods centerUnitNormal and volume(this for a face), while flux
is (1,1,1) everywhere.<br>
I expect 0 over the entire mesh and this is true on the coarse
grid, but for a refined grid this is not true for coarse cells
sharing intersections with finer cells.<br>
Does anyone see something like this? And is there a cure? Am I
doing something wrong?<br>
<br>
Thanks for any hint.<br>
