SOFTWARE DEVELOPMENT
paCalc
paCalc provides a user interface for optimizing or sampling inputs for any command-line model.
• Automatic fitting of field data with Levenberg-Marquadt and Simplex methods
• Multiple constraints such as simple fits to data, derivative fits, or fitting results from multiple observations simultaneously
• Advanced statistical processing for confidence region estimation
Sampling (Sensitivity Analysis)
• Latin Hyper-Cube or Monte-Carlo sampling of uncertain parameters
• Definition of probabilistic density functions (PDFs) for uncertain input parameters. PDFs are selected from an available library with user-defined inputs or entirely user-defined.
Command Line
• paCalc can also be executed from the command line using Message Passing Interface (MPI) libraries for parallel processing.
paCalc was originally developed by Geofirma staff for use on the Yucca Mountain program, and has since been modified for use by other clients. Continued development has been performed under Geofirma’s ISO 9001 certified QMS. paCalc can be purchased by contacting John Avis. Support and training are also available.
