This paper investigates the magnetohydrodynamic (MHD) stagnation point flow of Jeffrey material towards a nonlinear stretching surface with variable surface thickness. Heat transfer characteristics are examined through the melting process, viscous dissipation and internal heat generation. A nonuniform applied magnetic field is considered. Boundary-layer and low magnetic Reynolds number approximations are employed in the problem formulation. Both the momentum and energy equations are converted into the non-linear ordinary differential system using appropriate transformations. Convergent solutions for resulting problems are computed. Behaviors of various pertinent parameters on velocity and temperature distributions are studied in detail. Further the heat transfer rate is also computed and analyzed.
