I´ve got a question about postprocessing. I've run a magneto-harmonic 2d Simulation with linear triangle elements. Now I want to calculate the eddy current losses
$P = Re ( \frac{1}{2 \sigma} \int \int_\Delta J J^* dx dy ) $
In a book I found an equation for the integration with linear triangular elements
Hi,
I´ve got a question about postprocessing. I've run a magneto-harmonic 2d Simulation with linear triangle elements. Now I want to calculate the eddy current losses
$P = Re ( \frac{1}{2 \sigma} \int \int_\Delta J J^* dx dy ) $
In a book I found an equation for the integration with linear triangular elements
$P_e = \frac{\sigma}{2 \Delta} ( |J_i|^2 + |J_j|^2 + |J_k|^2 ) + Re( \frac{1}{2} ( J_i J_j^ + J_i J_k^ + J_k J_i^ +J_j J_k^ + J_j J_i^ + J_k J_j^ ) )$
with the current density $J = j \omega \sigma A$ and vector potential A given at the three nodes $i, j, k$
This works well but I wonder if there is a more simpler way to do this with skfem - even if you want to use other elements.
