CadnaA allows to handle projects of any size. There are practically no limits set by the software regarding number of objects (sources, buildings, contour lines, receiver points etc.). A large refinery with thousands of sources is just as easily assessed as cities or entire regions with numerous buildings and complex ground model. All project data are stored very conveniently in one file also including all project variants. This also allows very easy administration of different scenarios.
The only limitation for large projects is due to hardware memory. To break this one, CadnaA offers powerful features (PCSP technology for distributed calculation) and extensions (Option CALC: Networked distributed calculation). In fact with CadnaA you can handle projects of any size.
