The official homepage for the uqFEM is https://simcenter.designsafe-ci.org/research-tools/uqfem-application/

The uqFEM application is intended to advance the use of uncertainty quantification and optimization within the field natural hazards engineering. The application achieves this by combining existing finite element applications, e.g. FEAPpv, with uncertainty quantification (UQ) applications, e.g. Dakota, behind a simple user interface (UI). The combined application will enhance the finite element applications with uncertainty quantification and optimization capabilities. To overcome the issue of computational overhead, which typically precludes these types of probabilistic analysis from being performed, the user has the option of specifying that the simulations take place on HPC resources, e.g. the TACC Stampede supercomputer made available through DesignSafe-ci.

The specific types of analyses that the uqFEM application provides are:

  • Uncertainty Quantification
  • Calibration and Bayesian Calibration
  • Optimization
  • Sensitivity

The SimCenter is supported by a grant from the National Science Foundation (#1612843).
