I have done a magnetic computation involving Eddy currents. I would like
to compute the power dissipated by the Eddy current in the structure
sigma*(d A/d t)^2 over the entire geometry, how can I implement this
integral in the post-operation of the computation?, I actually do not
know how to get the temporal derivative of the potential vector A.
