AB: During May 1997 active region AR 8038 was the site from which all solar flares originated. In particular, on May 12 a halo CME was associated with the only major flare of the day. We present a study of the thermal structure of AR 8038 obtained using our computational MHD model. Our algorithm solves the resistive and viscous full MHD equations in 3D. The energy equation includes thermal conduction parallel to the magnetic field, a radiation loss term, and parametric heating. The surface magnetic flux is prescribed as boundary condition. The initial potential field is sheared to obtain an energized configuration. Then we advance the MHD/thermodynamic model and look for a steady state. From the plasma properties it is possible to calculate emissions in the extreme ultraviolet and X-ray bands and compare the images with the observations.
