Version 4.0.0

Major Changes Required for interfacing with DesignSafe the newly released Version 3 of Tapis. Updated major version to reflect Preferences need updating, and that for users submitting jobs to TACC HPC resources additional set-up steps and user input is required.

This work is based on material supported by the National Science Foundation under grants CMMI 1612843 and 2131111

Version 3.4.0

New for Version 3.4.0:

Option for multi-fidelity Monte Carlo.

Version 3.3.0

Major Changes to quoFEM for Version 3.3.0:

1. Multimodel uncertainty propagation
2. Stochastic kriging without replications
3. Display of correlation coefficients within the input/output dataset

and SimCenterBackendApplications: a4d0c1f3413eb6a0e105519abb4b78fc9159cab8

Version 3.2.0

Major Changes:

1. UQ Options:

• Support for a gradient-free optimization method
• Support for stochastic Kriging
• Fast global sensitivity analysis for very high dimensional output (tested on 2 million QoIs)

2. FEM

• "None" option for FEM that can be used when creating surrogates if user has data for which surrogate is required.

3. Misc

• New option to discard working directories after each model simulation
• Significantly enhanced speed of surrogate validation and prediction
• Improved user interface including error bounds of the surrogate prediction
• Renaming of options:
  (1) OpenseesPy->python (FEM), (2) Parameters estimation -> deterministic calibration (UQ/Dakota), (3) Inverse problem -> Bayesian calibration (UQ/Dakota)

• Improvements to reliability analysis and global sensitivity analysis user interface

• Minor bug fixes in the user interface, surrogate modeling, and sensitivity analysis scripts

Version 3.0.0

Changes:

• New option for surrogate modeling using Probabilistic Learning on Manifolds (PLoM)
• Restructured surrogate model scripts
• Improvements to the user interface for RV, QoI and RES tabs
