Applying a Time-dependent Data-driven Magnetofrictional Model to Multiple Active Regions

This study is centred around the comparative analysis of results from time-dependent data-driven magnetofrictional simulations of multiple active regions and related solar eruptions. We generated a time series of electrograms, ie photospheric electric field maps, by processing HMI vector magnetograms with the Electric Field Inversion Toolkit (ELECTRICIT). The electrograms were then used as the lower boundary condition to drive our simulations. The resulting dynamics are analysed by computing maps of the squashing factor and twist, and by calculating coronal metrics such as the volume energy and helicity, allowing for similarities and differences to be explored.
