The investigation of stagnation point flow in viscoelastic fluid through a vertical sheet with Soret and Dufour effects is the focus of this study. Stream functions and similarity variables simplify the governing partial differential equations into ordinary differential equations. The model is then integrated using the MATLAB built-in solver bvp4c. In graphs and tables, the solutions for temperature profile, velocity distribution, and mass concentration, as well as their gradients at the surface, are depicted under the influence of emergent parameters that occurred in the flow equations. Physical reasoning is used to discuss the physical attitudes of physical unknown quantities of interest under the influence of various parameters. The results show that raising the viscoelastic parameter K leads to an increase in temperature and concentration profiles, but to a decrease in velocity for assisting flow. Opposing flow has a similar occurrence, with minor differences. The graphical results show that as the Dufour number Du is increased for assisting flow, fluid velocity and temperature increase with no discernible change in concentration profile. The temperature and concentration profiles intensify with increasing Du behavior in the situation of opposing flow velocity. It's worth noting that when the Soret number Sr is increased, the velocity curves increase, but the opposite is true for temperature and concentration profiles. Physical quantities' attitudes toward the above-mentioned parameters are in line with physical phenomena.
