             abstract = "We use a global magnetohydrodynamics simulation to analyze 
                         transient magnetic reconnection processes at the magnetopause. The 
                         solar wind conditions have been kept constant, and an 
                         interplanetary magnetic field with large duskward BY and southward 
                         BZ components has been imposed. Five flux transfer events (FTEs) 
                         with clear bipolar magnetic field signatures have been observed. 
                         We observed a peculiar structure defined as interlinked flux tubes 
                         (IFTs) in the first and fourth FTE, which had very different 
                         generation mechanisms. The first FTE originates as an IFTs and 
                         remains with this configuration until its final moment. However, 
                         the fourth FTE develops as a classical flux rope but changes its 
                         3-D magnetic configuration to that of IFTs. This work studies the 
                         mechanism for generating IFTs. The growth of the resistive tearing 
                         instability has been identified as the cause for the first IFTs 
                         formation. We believe that the instability has been triggered by 
                         the accumulation of interplanetary magnetic field at the subsolar 
                         point where the grid resolution is very high. The evidence shows 
                         that two new reconnection lines form northward and southward of 
                         the subsolar region. The IFTs have been generated with all the 
                         classical signatures of a single flux rope. The other IFTs 
                         detected in the fourth FTE developed as a result of magnetic 
                         reconnection inside its complex and twisted magnetic fields, which 
                         leads to a change in the magnetic configuration from a flux rope 
                         of twisted magnetic field lines to IFTs.",
