VECMA VVUQ Toolkit Month 15 release: FabSim3, EasyVVUQ, QCG and Application Tutorials


Welcome to the dedicated website for the VECMA Toolkit (VECMAtk).

This is the initial release of VECMAtk, which aims to facilitate Verification, Validation and Uncertainty Quantification (VVUQ) for complex single- and multi-scale applications. This is the first of three annual releases planned over the duration of the VECMA project ( The Toolkit release contains a suite of components, providing tools to:

  • create VVUQ procedures (EasyVVUQ),
  • to automate the complex workflows emerging from these procedures (FabSim3),
  • to enable the efficient execution of large numbers of jobs on computational resources (QCG Pilot Job Manager),
  • and to provide convenient means to use HPC facilities for users (QCG-Now) and user-developers (FabSim3 and QCG-Client).

See the Toolkit tab for more details on these components, and the Release History tab for an overview of the current and all previous releases.

We have been developing the software toolkit to enable automated VVUQ, providing support for software applications regardless of the domain of interest. We have established a collection of readily working algorithms for uncertainty quantification within existing multiscale computing tools. We provide tutorials in four application areas as part of this initial release.
