1. Local Data-driven MHD Simulations of Active Regions W.P. Abbett MURI 8210 Workshop Mar 2004

2. Primary Challenges of Data-driven modeling: ► Determining electric fields and flows consistent with the observed evolution of the magnetic field at the photosphere (Welsch, Fisher, Longcope, Demoulin) ► Generating initial atmospheres consistent with X-ray observations of the corona (McTiernan, Liu, Regnier, Lunquist) ► Developing a physically-consistent means of incorporating newly emerging flux from a separate system into fully magnetized atmospheres (Abbett, Mikic, Linker, Fisher) ► Developing standard techniques of testing and validating the new methods (Abbett, Magara, Fisher, Welsch, Bercik)
