Documentation of UCODE; a computer code for universal inverse modeling
E. P. Poeter, Mary Catherine Hill · 1998
The computer code described in this report is designed to allow inverse modeling, posed as a parameter estimation problem, using existing application models.Although designed using ground-water models, the code can be used in conjunction with other application models that use ASCII or text only input, produce ASCII or text only output, and can be executed in batch mode.The performance of UCODE has been tested in a variety of applications.Future applications, however, might reveal errors that were not detected in the test simulations.Users are requested to notify the originating office of any errors found in the report or the computer program.Updates might occasionally be made to both the report and to UCODE.Users can check for updates on the Internet at URL http://water.usgs.gov/software/ground_water.html/.
