Hello Alexander,
Do you solve problem with varying conductivity only or magnetic
permittivity and electric permeability can also be functions of position?
I have done both cases.
For magnetic permittivity to vary one needs: curl(mu*curl(E))
I'm not sure how to do this and it's not clear from this:
http://www.dealii.org/developer/doxygen/deal.II/namespaceLocalIntegrators_1_1Maxwell.html#a0f6ee26697d50234f1642f903d4cfd8a
It looks like the LocalIntegrators are not capable of this case yet.
Thus, you can extend this function to cover also this case (which is
quite easy) or doing the assembling by hand (as I always do).
I meant standard KellyErrorEstimator. I would need to implement other
schemes myself? This is not a problem, just would be better to know in
advance.
I doubt that the KellyErrorEstimator is a good choice. However I do not
know of anyone, who ever tried this, and thus it might suffice your
needs. Nevertheless, better results can be expected by a residual-based
or goal-oriented a posteriori error estimator for Maxwell's equations.
Best Regards,
Markus
