We propose a self-consistent micromagnetic model that dynamically solves the Landau-Lifshitz-Gilbert equation coupled to the full spin-diffusion equation. The model and its finite-element implementation are validated by current driven motion of a magnetic vortex structure. Potential calculations for a magnetic multilayer structure with perpendicular current flow confirm experimental findings of a non-sinusoidal dependence of the resistivity on the tilting angle of the magnetization in the different layers. While the sinusoidal dependency is observed for certain material parameter limits, a realistic choice of these parameters leads to a notably narrower distribution.
