DESCRIPTION:Speakers: Indranil Das (CERN)\nThe high granularity calorimete
 r (HGCAL) of CMS is planned to operate during the high luminosity operatio
 n of the LHC\, replacing the existing electromagnetic and hadronic calorim
 eters at the endcap section. It will enable a detailed investigation of ve
 ctor boson fusion processes and Lorentz-boosted topologies in forward regi
 ons. An extensive validation of the hardware and software components of th
 is state-of-the-art calorimeter is currently in progress.\n\nIn this prese
 ntation we describe some of the interesting and complex details that need 
 to be included in a high quality simulation of the calorimeter. We have de
 veloped a muon tomography technique that is found to be very useful for id
 entifying any problems after changes are made as well as for testing the c
 orrectness of the geometry. We discuss how this technique is used to figur
 e out energy loss discrepancies with partial-wafer silicon sensors\, incor
 rect rotation of full and partial-wafer silicon sensors\, and validation o
 f GEANT hit positions in the HGCAL scintillator tiles.\n\nhttps://indico.t
