CMS geometry preparation

 

The CMGEO flow diagram is presented below. This part interfaces with UGINIT via a call to DCMSGEOM and tries to read constants structure from the input GEANT.RZ file (using IODB key word ``DETI'' and ``RGET'' as a control card). If the requested file does not exist or there are any problems with the GEANT structure then the program recreates this structure using title data file(s) and saves them (structures) optionally as the output GEANT.RZ file (using IODB keyword ``DETO'' and ``RSAV'' as the control card).
