The SICS unit main activity is the optimizing and assisting in the development of CIRA in-house codes.Among them a prominent place belongs to CFD finite volume codes, whose development began in the '90s using Fortran 77 language. The current codes have inherited the original structure updating and improving the CFD models. Conversely, the software language remained largely unchanged and it has not taken into account, except in small part, on progress in programming languages. This leads to inefficiencies in terms both of computational speed and of memory and disk space management.
In the case of CFD codes CIRA SICS work is divided into the following phases:
