Beam De­liv­ery Sim­u­la­tion (BDSIM) is a pro­gram based on Geant4 that cre­ates 3D ra­di­a­tion trans­port mod­els of ac­cel­er­a­tors from a sim­ple op­ti­cal de­scrip­tion in a vastly re­duced time frame with great flex­i­bil­ity. It also uses ROOT and CLHEP to cre­ate a sin­gle sim­u­la­tion model that can ac­cu­rately track all par­ti­cle species in an ac­cel­er­a­tor to pre­dict and un­der­stand beam losses, sec­ondary ra­di­a­tion, dosi­met­ric quan­ti­ties and their ori­gin. BDSIM pro­vides a li­brary of scal­able generic geom­e­try for a va­ri­ety of ap­pli­ca­tions. Our Python pack­age, Pyg4om­e­try, al­lows rapid prepa­ra­tion and con­ver­sion of geome­tries for BDSIM and other ra­di­a­tion trans­port sim­u­la­tions in­clud­ing FLUKA. We pre­sent a broad overview of BDSIM de­vel­op­ments re­lated to a va­ri­ety of ex­per­i­ments at sev­eral fa­cil­i­ties. We pre­sent a model of the for­ward ex­per­i­ment FASER at the LHC, CERN where the geom­e­try is com­pos­ited from mul­ti­ple sources using Pyg4om­e­try. The analy­sis of par­ti­cle his­tory is pre­sented as well as pro­duc­tion mech­a­nisms. We also pre­sent the ap­pli­ca­tion of re­cently in­tro­duced laser in­ter­ac­tions in Geant4 to Comp­ton pho­tons from a laser­wire di­ag­nos­tic at the ATF2.
