The study of time-dependent solar active region morphology and its relation to eruptive events requires analysis of imaging data obtained in multiple wavelength domains with differing spatial and time resolutions, ideally in combination with 3D physical models. To facilitate this goal, we have undertaken a major enhancement of our IDL-based simulation tool, GX Simulator, originally developed for modeling microwave and X-ray emission from flaring loops (Nita et al. 2015), to allow it to simulate quiescent emission from solar active regions.
GX Simulator is publicly available as part of the SolarSoftWare (SSW) IDL repository. The object-based architecture of GX Simulator, which runs on Windows, Mac and Linux platforms, provides an interactive graphical user interface that allows the user to import photospheric magnetic field maps as input to the magnetic field extrapolations within the tool, or alternatively to import 3D numerical magnetic field models. The magnetic skeleton may be populated with thermal plasma by importing 3D density and temperature distribution models or, alternatively, by assigning to each individual volume element numerically defined differential emission measure (DEM) distributions inferred from parametric heating EBTEL models (Klimchuk et al. 2008) that assume either steady-state or impulsive nanoflare plasma heating.
The application integrates shared-object libraries containing ...
