Documentation and User's Guide: GS2 (Two-Dimensional Version) and GS3 (Three-Dimensional Version) - Variably Saturated Flow and Mass Transport Models. Final Report (Including 3 Example Problems).

摘要

The report presents documentation and a user's manual for programs GS2 (two-dimensional version) and GS3 (three-dimensional version). Mathematical equations and physical principles utilized to develop the code are presented in Section 2. The numerical approach used (Galerkin Finite Elements) is presented in Section 3. Section 4 presents an overview of how problems should be set up to properly use the code while detailed input instructions are presented in Section 5. Output produced by the code is discussed in Section 6. Three example problems, including sample input data sets and output data, are presented in Section 7. Program information is provided in Section 8. The report was prepared as part of a project in which NRC staff was presented a training course on how to properly use the computer program. Programs GS2 and GS3 can be utilized to analyze flow and mass transport in unsaturated, partially saturated, or fully saturated flow regions.
