We simulate the propagation of relativistic test particles within the field of a 3D MHD simulation of the solar wind. The adiabatic ideal MHD equations are integrated numerically using the MPI-AMRVAC code. Test particles are initialized within the MHD simulation grid and advanced in time according to the guiding center equations, we employ a third-order accurate time prediction-correction method from Mignone et al. 2023 for integration. We also include possibility of diffusion in velocity space based on a particle-turbulence mean free path λ∥ along the magnetic field line. One of the first results where we consider 81 keV electrons injected at 0.139 AU heliocentric distance and mean free path λ∥ = 0.5 AU is in good qualitative agreement with measurements at 1 AU.
