Objective: to determine the connectivity changes, observable signatures, and energy budget of flare reconnection driven by a self-consistent solar eruption. Results can be used as input for particle acceleration models and compared with SEP and radio observations.

Methods: numerical simulations with ARMS, our massively parallel 3D MHD code with adaptive mesh refinement. Postprocessing with Heliospace and other software to determine field topology and predict observable signatures.

Significance: understanding the 3D reconnection process through modeling driven in a self-consistent and realistic manner is an essential component of a team approach to solving the flare particle acceleration problem.
