OpenTURNS is a Unix/Linux software with two main components :

- a scientific C++ library including an internal data model and algorithms dedicated to the treatment of uncertainties. The main function of that library is giving to specific applications all the functionalities needed to treat uncertainties in studies. Targeted users are all engineers who want to introduce the probabilistic dimension in their so far deterministic studies.

- a python module with high level operators in the probabilistic and statistical field. The interest of this language is to be both a powerful scientific language (capable of using C++ libraries), and a user friendly interpreted language like Matlab’s one. This python module was designed to make the development of prototypes easier (in order to test new algorithms and methods for example), to become an easy-to-use support for educational works, … This module intends to become a natural environment capable of integrating new developments with
