Thanks a lot, it works perfectly.

Another question (I feel free to ask, sorry if it's too lame..) is: how to
compute volume (area) of 2D deformed elastic body? Of course using
CellIterator->volume(), but how to update the mesh to displacement field?
There is movemesh() function in freefem++ `language`, does dolfin  deal with
an equivalent one? I hope it is possible to deform mesh without interfering
with each point coordinates...

cheers
