ITHACA-FV (In real Time Highly Advanced Computational Applications for Finite Volumes) is C++ library based on the finite volume solver OpenFOAM . It consists of the implementation of several reduced order modeling techniques for parametrized problems. ITHACA-FV is developed and maintained by Dr. Giovanni Stabile under the supervision of Prof. Gianluigi Rozza at SISSA mathLab an applied math laboratory of the International School for advanced studies .
