NOSA-ITACA results from the integration of the finite element code NOSA with the open source interactive graphic code SALOME, used both to define the geometry of the structure under examination and to visualise the results of the structural analysis.

NOSA-ITACA can be used to study the static and dynamic behaviour of masonry buildings of historic and architectural interest and model the effectiveness of strengthening operations. The code is at the disposal of private and public bodies operating in the field of the conservation and safeguarding of the cultural heritage.
