Magnetic reconnection plays a major role in determining the dynamics of the magnetosphere. Yet, the reconnection rate in most global magnetosphere models relies on numerical resistivity. This means, unfortunately, that the simulation results are sensitive to the numerical parameters, such as grid resolution and the choice of the numerical scheme. We are exploring how we can control the resistivity in a better way. As a preliminary study, we do grid convergence studies of reconnection with constant resistivity in 2 dimensions. We establish the relationship between the grid resolution and the achievable magnetic Reynolds number. Based on these results we can estimate the effective numerical resistivity in global magnetospheric simulations, and use an explicit resistivity to better control the reconnection rate.
