Hi, you may use a line integration in derived value when you doing the postprocessing , and the variable to be integrated can be an expression of Axt,Ayt and Azt, the "t" here means the time derivative, and Ax,Ay,Az are the three component of magnetic vector potential, and perhaps the expression could be written as "sqrt(Axt^2+Ayt^2+Azt^2)", I am not sure, wish it works!<br />
Good Luck!Sat, 17 Aug 2013 06:07:29 +000038523.1376719649.106746Partial integration in full integration

Hello all,<br />
<br />
I am trying to calculate the induced voltage in a coil in the time domain, the formula is:<br />
<br />
V=int(part(A)/part(t)dl)<br />
<br />
i hope you get the idea, that is a line integral for one filament of a coil, dl being part of the length of the wire. i need to integrate the partial magnetic vector potential (A) for each time step along the wire. Fri, 19 Jul 2013 06:42:50 +000038523.1374216170.105765
