flare_equilibrium_m Module

Equilibrium based on FLARE: (field line analysis and reconstruction for 3D boundary plasma modeling) see H. Frerichs 2024 Nucl. Fusion 64 106034 DOI 10.1088/1741-4326/ad7303

The source code of FLARE needs to be compiled separately https://gitlab.com/hfrerichs/flare (stable with #4351aff722f9d2b7495211f09f774bc406064ac1)

FLARE relies on MOOSE, which needs to be compile seperately, too. https://gitlab.com/hfrerichs/moose.git (stable with #4c4a046b615ba19f68e1c1003c975941db7c6cf7)

All routines or variables that are provided externally from FLARE are imported with the prefix "FLARE_"
