  The newly discovered galaxy cluster 1RXS J0603.3+4214 hosts a 1.9 Mpc long,
bright radio relic with a peculiar linear morphology. Using hydrodynamical
+N-body AMR simulations of the merger between three initially hydrostatic
clusters in an idealised setup, we are able to reconstruct the morphology of
the radio relic. Based on our simulation, we can constrain the merger geometry,
predict lensing mass measurements and X-ray observations. Comparing such models
to X-ray, redshift and lensing data will validate the geometry of this complex
merger which helps to constrain the parameters for shock acceleration of
electrons that produces the radio relic.
