The interpretation of the measured energy spectrum, composition and arrival direction of ultra-high energy cosmic rays (UHECRs) above ∼ 1017 eV is still under controversial debate. The development and improvement of numerical tools to propagate UHECRs in galactic and extragalactic space is a crucial ingredient to interpret data and to draw conclusions on astrophysical parameters. In this contribution recent developments of the publicly available propagation code CRPropa 3 are outlined. Examples are given for 1D and 3D simulations in structured magnetic fields including secondary messengers such as photons and neutrinos. To take into account cosmological effects, also 4D simulations are possible and discussed in the talk.
