AB In this paper, we investigated magnetohydrodynamic (MHD) thin film flow of an Oldroyd-B fluid in the presence of heat transfer with effect of viscous dissipation over an oscillating vertical belt. The fluid is assumed to be unsteady, and the basic governing equations are modeled in the form of nonlinear coupled partial differential equations with pertinent initial and boundary conditions. For the analytical solutions of the problem we use the optimal homotopy asymptotic method (OHAM). For comprehension, the physical presentation of such modeled parameters as the Prandtl number Pr, Brinkman number Br, time retardation parameter a, time relaxation parameter β, gravitational parameter S_{t}, and magnetic parameter M are plotted graphically and discussed. An increase in M increases the velocity and temperature distribution, the boundary-layer thickness decreases by increasing the Prandtl number, and the velocity decreases by increasing the gravitational parameter.
