In this Master's thesis the effect of magnetic reconnection at the magnetopause is investigated while considering non-ideal effects such as resistivity and viscosity. The analysis is conducted at the dayside magnetopause, but off the subsolar point resulting in a non-zero magnetosheath flow influencing the flow structure. Also a velocity gradient is introduced affecting the structure further. It is shown the the structure of the magnetic field and streamlines are dramatically changed from the symmetric ideal case.Validerat; 20101217 (root
