THE GRAPHICAL USER INTERFACE OF OPENTURNS, A UQ SOFTWARE IN SIMULATION

The number of software for uncertainty quantification is already substantial, and this number is growing. OpenTURNS, for example, is a C++ library for uncertainty propagation by probabilistic methods. OpenTURNS is also available as a Python module and has gained maturity thanks to more than 10 years of development. However, there are situations where we do not want to use a programming language such as C++, Python (e.g. OpenTURNS) or Matlab. In this context, providing a graphical user interface (GUI) may allow to greatly increase the use of OpenTURNS and, more generally, of the UQ methodology. In this talk, we will present how OpenTURNS’s GUI is integrated into SALOME, a platform for pre and post-processing of numerical simulations. Through examples, we will discuss the main features of the tool: central dispersion analysis, global sensitivity analysis and threshold probability estimate. Other advanced features will be presented during the session, with the aim of seeing how the tool can be used during training sessions or within a HPC context for example.
