A simulation was carried out on an unsteady flow of a viscous, incompressible and\nelectrically conducting fluid past an infinite vertical porous plate. A generic computer\nprogram using the Galerkin finite element method is employed to solve the\ncoupled non-linear differential equations for velocity and temperature fields. The\ndiffusion equation, the energy equation, the momentum equations and other relevant\nparameters are transformed into interpretable postfix codes. Numerical calculations\nare carried out on the flow fields both in the presence of cooling and heating of the\nplate by free convection currents. The effects of the dimensionless parameters,\nnamely, the Prandtl number, the Eckert number, the modified Grashof number, the\nSchmidt number and the time on the temperature and velocity distributions are discussed.
