The present paper contains the untapped characteristics of the thermally magnetized grooved computational domain. To be more specific, in this paper the uniformly heated circular-shaped cylinder is placed fixed towards ongoing cold Newtonian fluid. Two uniformly heated rectangular ribs are installed to attain grooved geometry. Further, it is assumed that the cold fluid enters from an inlet of the channel with the parabolic velocity profile. The outlet of the channel is carried with Neumann condition. All other walls are taken with no-slip condition. The energy equation is incorporated to examine the heat transfer individualities. In this regard, the left wall is taken cold while the right wall is carried with an adiabatic condition. The whole physical design is translated in terms of partial differential equations and for solution purpose, the finite element method is utilized. For a better approximation, we have carried hybrid meshing. The outcomes are shared by way of contour plots and line graph study. The impact of the magnetized flow field and the heated rectangular ribs on hydrodynamic forces experienced by the circular obstacle is examined. The statistics for hydrodynamic forces in terms of lift and drag coefficients are offered up-to five different meshed levels. Such values are recorded by adopted line integration around the outer surface of the obstacle.
