GASDYN – software

Simulation software for internal combustion engines

The numerical code named GASDYN has been developed since 1996 at the Department of Energy of Politecnico di Milano. It is based on simulation programs for internal combustion engines. The model allows a 1D (one-dimensional) simulation of unsteady reacting flows in the intake and exhaust systems of internal combustion engines, both Otto and Diesel cycle, naturally aspirated or turbocharged, including the after-treatment systems and silencers.
From 1996 to 2014 the GASDYN code has been continuously developed and integrated with innovative aspects by the IC Engine Research Group at the Department of Energy (A. Onorati, G. D’Errico, G. Montenegro, T. Lucchini, F. Piscaglia, T. Cerri, A. Della Torre, A. Montorfano – ICEGroup,
Over the time the GASDYN code has become known in the scientific context and among automotive companies in Italy and abroad (Europe, USA).
Over the years it has been developed also a “user-friendly” graphical interface called GASDYN-Pre (shown) that allows, through the setting of engine parameters, to generate those values then the GASDYN code uses in the simulation.
Recently a partnership has been established with EXOTHERMIA for further development and global commercial distribution of GASDYN code. EXOTHERMIA is a known spin-off company of Aristotle University of Thessaloniki (Greece), with offices in Greece and Germany, specializing in the simulation of engines emission control, developing and delivering globally the software AXISUITE.
