Dear Daniel,<br>
<br>
For this, you should use GlobalQuantities. Here are your files extended
for this purpose.<br>

<p class="MsoNormal">I am trying to solve an electrical conduction
problem, a
simplified version of which I present here. I have a conducting bar,
with
two contacts held at fixed potential. I have no trouble calculating
scalar voltage, E field and current density. I am struggling, though,
with integrating the current density over a cross-section of the bar to
measure
total current. I have set up the bar 1cm dia and 10cm long, with half
on
either side of the X-Z plane. I can integrate 1 over the cross section
at
the X-Z plane and correctly derive the cross-sectional area of the bar
(after
correcting with 2pi geometry factor for global quantity inAxiSymmetric
problem).
When I try to integrate current, I get 0 as a result - because E field
isn't
defined on the line element I use as my cross-section cut-plane. I am
not
sure how to resolve this - either how to get E field (thus, current)
defined on
the cut-plane or define the integration differently. Any help is
greatly
appreciated - thank you!<o:p></o:p></p>
