The pull request https://github.com/jbeirer/FastCaloSim/pull/17 introduced the ATLAS magnetic field. It was necessary to introduce a small_move_to_ID method for the IDCaloBoundary that shifts the position (by a very small amount) into the ID. If this is not done, particles seem to remain unaffacted by the magnetic field. This needs to be discussed with Geant4 experts.
