Query: A Numerical Simulation of the Reconnection Layer in 2D Resistive MHD   In this paper we present a two-dimensional, time dependent, numerical
simulation of a reconnection current layer in incompressible resistive
magnetohydrodynamics with uniform resistivity in the limit of very large
Lundquist numbers. We use realistic boundary conditions derived consistently
from the outside magnetic field, and we also take into account the effect of
the back pressure from flow into the the separatrix region. We find that within
a few Alfven times the system evolves from an arbitrary initial state to a
steady state consistent with the Sweet--Parker model, even if the initial state
is Petschek-like.
