STEREO represents a quantum leap from the perspective of the simulations. By providing a 2-satellite view it will be able to determine the true 3D stereoscopic view of the structure of the magnetic field lines and to investigate the motions of the field lines. A crucial issue among the key mission objectives is the study of reconnection and coronal mass ejections. The theory of 3D magnetic reconnection is still far from being fully developed. But a pivotal aspect is the role played by null points in the topology changes induced by reconnection [1]. STEREO will provide a unique opportunity to look directly at this issue. We will investigate the role of null points using our simulation tool, FLIP-3D [2], and our diagnostic tools to pick up null points and to study Poincare plots. We will provide evidence of the type of theoretical predictions [3] that will be best compared with STEREO observations. [1] Y. Lau, J. Finn, ApJ, 350, 672 (1990) [2] J.U.
