  To fully un­der­stand the beam losses, sub­se­quent ra­di­a­tion, en­ergy de­po­si­tion, back­grounds and ac­ti­va­tion in par­ti­cle ac­cel­er­a­tors, a holis­tic ap­proach com­bin­ing a 3-D model, physics processes and ac­cel­er­a­tor track­ing is re­quired. Beam De­liv­ery Sim­u­la­tion (BDSIM) is a pro­gram de­vel­oped to sim­u­late the pas­sage of par­ti­cles, both pri­mary and sec­ondary, in par­ti­cle ac­cel­er­a­tors and cal­cu­late the en­ergy de­posited by these par­ti­cles via ma­te­r­ial in­ter­ac­tions using the Geant4 physics li­brary. A Geant4 ac­cel­er­a­tor model is built from an ex­ist­ing op­ti­cal de­scrip­tion of a lat­tice by pro­ce­du­rally plac­ing a set of pre­de­fined ac­cel­er­a­tor com­po­nents. These generic com­po­nents can be re­fined to an ar­bi­trary de­gree of de­tail with the use of user-de­fined geome­tries, de­tec­tors, field maps, and more. A de­tailed model of the Large Hadron Col­lider has been cre­ated in BDSIM, val­i­dated with ex­ist­ing track­ing codes and ap­plied to study beam loss pat­terns.
