Query: Performance Analysis of FEM Solvers on Practical Electromagnetic
  Problems   The paper presents a comparative analysis of different commercial and
academic software. The comparison aims to examine how the integrated adaptive
grid refinement methodologies can deal with challenging, electromagnetic-field
related problems. For this comparison, two benchmark problems were examined in
the paper. The first example is a solution of an L-shape domain like test
problem, which has a singularity at a certain point in the geometry. The second
problem is an induction heated aluminum rod, which accurate solution needs to
solve a non-linear, coupled physical fields. The accurate solution of this
problem requires applying adaptive mesh generation strategies or applying a
very fine mesh in the electromagnetic domain, which can significantly increase
the computational complexity. The results show that the fully-hp adaptive
meshing strategies, which are integrated into Agros-suite, can significantly
reduce the task's computational complexity compared to the automatic
h-adaptivity, which is part of the examined, popular commercial solvers.
