Poynting vector

Patrick Kappl requested to merge PatrickKappl/openpixi_c:poynting_vector into master

This merge request adds:

  • a new way to calculate the magnetic energy density.
  • a testcase for the dot product of two algebra elements.
  • a diagnostic to calculate the Poynting vector. Here 4 different modes are possible: the standard ExB or the result derived from the discrete energy density. Both can be calculated at the time of the E-fields or the plaquettes.
  • a diagnostic to calculate the projected power density, which uses the results of the projected energy density diagnostic.
  • a diagnostic to calculate the projected divergence of the Poynting vector, which uses the results of the Poynting vector diagnostic.
  • a test for Poynting's theorem.
