Hello,

I am not able to find a complete documentation about dolfin (might not be available yet).

My question is the following: Once I obtain the dolfin function u after solving the FE problem, how could I obtain the square of all the values? This will be useful since I am solving a differential equation for a field (u), but I am only interested in the field intensity (u^2) at each point.

Thank you,

Pol
