Hi,
thanks for all the advices.
Andreas, in order to redefine my problem: I want to manage curvilinear 
grid, then during refinement I would like to move new nodes on the 
curvilinear parametrization to get a smoother grid. To make this 
possible I should be able to move new vertices on the parametrization, 
but this would mean getting 5-vertices element as the first neighbours 
to the locally refined region.
o-----------o
|              |
|              |
|              |
o----m----o
|      |       |
n----n-----n
|      |       |
o----n---.-o
This would be the standard refinement, but I want to move the m-vertex 
on a parametrization of o----m----o, like this
o-----------o
|              |
|      m     |
|   /   |   \  |
o      |      o
|       |      |
n----n-----n
|      |       |
o----n---.-o
But now the element o-m-o-o-o has 5 vertices.
I don't want to avoid hanging nodes as you can see. But I think I can't 
manage 5-vertices elements with ALUGrid, isn't it? And with UG??
I cannot understand why this kind of element is hard to be managed. When 
an hanging node is present, let me say in the first configuration I 
plotted, I have 5 intersections anyway!
Does only UG allow me to move vertices?
What happen if 4 elements are coarsened? Do I get a 5-vertex element???
         o
     /   |   \
o      |      o
|       |      |
o----o-----o
|      |       |
o----o---.-o

Thanks a lot again!!
Cheers,
Marco
