Development of the elsA software for complex external and internal flow aerodynamics and multidisciplinary applications started in 1997 at Onera. Due to the multi-purpose nature of elsA, many common basic CFD features can be shared by a wide range of aerospace applications: aircraft, helicopters, turbomachinery, missiles, launchers… The elsA software is based on an Object- Oriented design method and on an Object-Oriented implementation based on three programming languages: C++, Fortran and Python. The elsA strategy...
