It would be useful to get the voltage/current along a 1D line. Possible implementation: - Use FEFieldFunction in deal.II (https://www.dealii.org/developer/doxygen/deal.II/classFunctions_1_1FEFieldFunction.html). This does exactly what we want but it may be slow. - Use DTK. It will probably faster but requires to finish the deal.II-DTK adapters.
