Automated sensitivity analysis with the Gradient Enhanced Software System (GRESS)
GRESS automates the implementation of the well-known adjoint method for performing a comprehensive sensitivity analysis of existing FORTRAN 77 computer models. The GRESS ADjoint matrix GENerator (ADGEN) option is used to calculate first derivatives and sensitivities of selected model results with respect to all input data. This report provides a small problem used to exercise most of the major program options for a GRESS/ADGEN application. A description of the input and output from each processing step as well as the method for controlling the application is presented. The report is designed to aid users of the GRESS ADGEN option. 6 refs., 4 figs., 2 tabs.
