Hi,
Usually I use the MagnetoDynamics2D harmonic solver for solving 2D high frequency Electromagnetics problems.
But by trying to make the Command Line "Induction heating of a graphite crucible" tutorial, I saw that a "StatMagsolver" is used.
Could somebody explain what is the difference between the MagetoDynamics2D solver and the StatMagsolver please?
Thanks in advance for your help.

Re: SatMagSolver vs MagnetoDynamics2D solver
Module name: StatMagSolve
Module subroutines: StatMagSolver
Module authors: Juha Ruokolainen, Ville Savolainen, Jussi Heikonen, Peter R˚aback, Antti Pursula
Document authors: Ville Savolainen, Peter R˚aback, Antti Pursula, Mika Malinen
76.1 Introduction
Note: This solver is obsolete!
Maxwell’s equations may generally be expressed by employing a scalar potential and a vector potential.
The magnetic flux density is then the curl of the vector potential. In some cases the effect of the scalar
potential vanishes and the system is fully described by the vector potential. These cases include magne-
tostatics problems where time-independent magnetic fields may be created by electromagnets with given
current distributions or permanent ferromagnets. The solver considered here allows the first option, with
non-homogeneous and non-linear magnetic materials.
The scalar potential may also be ignored in two-dimensional magnetoquasistatic cases when the current
density acts in a direction orthogonal to the plane considered. Then eddy current effects relating to a sinu-
soidal evolution of the current density may also be considered at low frequencies. If there are no conductors
in the system, this approximation reduces to the equations of magnetostatics.
This solver was historically developed for the axially symmetric cases and it should only be used in
those. For handling problems in orthogonal Cartesian coordinates, see the modules MagnetoDynamics
and MagnetoDynamics2D for 3-D and 2-D versions, respectively.
