We present a numerical algorithm for the incorporation of active cosmic ray transport into ZEUS-3D magnetohydrodynamical code. The is described by diffusion-advection equation. applied form diffusion tensor allows anisotropic rays along and across magnetic field direction, which controlled two parameters: parallel perpendicular coefficients. implemented tested comparison diffusive to analytical solutions Our method numerically stable wide range coefficients, including realistic values inferred from observational data Milky Way about . presented exemplary simulations Parker instability triggered injected single SN remnant.
