This continuation presents the applications of on-uniform heat source/sink and viscous dissipation in megnetohydrodynaimcs (MHD) flow of Casson nanoparticles toward a porous stretchable sheet. The flow model is presented in terms of governing expressions for which a non-dimensional transmuted set of expressions is retained by utilizing relevant similarities modification. These equations are numerically resolved by utilizing the famous shooting technique. The influence of numerous parameters such as Casson parameter, elastic parameter, porosity parameter, Prandtl number, non-uniform heat source/sink constant, Eckert number, skin fraction and Nusselt number on the flow area are examine and attain numerical outcomes are tabulated and illustrated with the help of graphs. The results reflect that the velocity of nanoparticles declined effective with porosity parameter and nanoparticles volume fraction. The temperature profile is enhanced with elastic parameter and heat source parameter while decay with Eckert number and Casson fluid parameter. Moreover, a declining change in wall shear force against nanoparticles volume fraction is observed when Hartmann number is maximum.
