In a nutshell

UQLab is a general purpose Uncertainty Quantification framework developed at ETH Zurich (Switzerland). It is made of open-source scientific modules which are smoothly connected to perform uncertainty quantification through Monte Carlo simulation, sensitivity analysis, reliability analysis (computation of rare event probabilities), surrogate models (polynomial chaos expansions, Kriging, etc.), Bayesian inversion/calibration and many more.

Since version 2.0, UQLab is released open source under the BSD-3 clause license

News
  • 1st February 2022: UQLab Version 2.0 is released! This release is now completely open source, so there is no distinction between academic or commercial user registration, nor any internet connectivity requirement. Additionally 2 new modules are available in UQLab: Stochastic spectral embedding  and Random fields !
     

  • 27 October 2021: UQLab 4000th user is an ETH Zurich student. Arijit Upadhyay, a master's student from India enrolled in the Energy Science and Technology program at ETH Zurich (Switzerland) is the 4,000th registered user of UQLab. Arijit plans to use UQLab to run some uncertainty analysis for his master thesis on the “assessment and uncertainty analysis of the role of hydrogen as a long-term storage medium and as a flexibility provider for the European electricity system”. This work is carried out at the Reliability and Risk Engineering Lab in the Department of Mechanical and Process Engineering of ETH Zurich. The top 3 countries in terms of UQLab usage are still United States (625 registered users), China (570) and France (360).
