AB: We report on the progress of 3D simulations of active region magnetic flux emergence (and decay) through the stratified, sub-photospheric layers of the upper convection zone into the solar atmosphere and low corona. We use a recently-developed 3D semi-implicit MHD code (with a non-uniform, adaptive mesh) to address the inherent stiffness of the system of equations, and will compare our results with similar studies using second-order accurate, fully explicit numerical schemes.
