Energetics and Emission in a Simulated Solar Flare Initialised by a Non-Force Free Magnetic Field
Non-force-free initial fields let flare simulations release twice the magnetic energy and match observed EUV emission more closely than standard force-free setups.

Claims
the non-force free model undergoes more extensive magnetic restructuring and releases approximately twice as much magnetic energy (≈4.4 × 10^31 erg) as the NLFF case (≈2.3 × 10^31 erg), bringing the energy budget into closer agreement with expectations for X-class flares. The non-force free model produces a brighter and more spatially extended emission structure that more closely resembles the observed flare morphology and light curve.
That the only meaningful difference between the two runs is the initial magnetic configuration and that the non-force-free extrapolation accurately captures the real pre-flare coronal field without introducing uncontrolled numerical or physical artifacts.
Non-force-free initial magnetic fields in solar flare simulations release about twice the magnetic energy and yield EUV emission closer to observations than conventional NLFF extrapolations.
