FePEST - a convenient graphical user interface for using PEST by John Doherty with FEFLOW models - is now included with every FEFLOW license.

With FePEST it is possible to use a range of PEST functionality without the need to learn the syntax of PEST's command lines and configuration files and to manually adapt FEFLOW's model files for usage in PEST. Its advantages include graphical support during the setup process and immediate graphical feedback on the simulation progress.

The range of supported PEST features in FePEST which is part of FEFLOW version 6.2 includes:

• Model calibration (including regularization and pilot-point parametrization)
• Subspace methods
• Parallel execution (locally and/or using remote servers, incl. file transfer)
• Linear sensitivity analysis
• Predictive analysis (worst-/best-case scenarios)
