3. DESCRIPTION OF PROBLEM OR FUNCTION

SWIFT solves the coupled or individual equations governing fluid flow, heat transport, brine displacement, and radionuclide displacement in geologic media. Fluid flow may be transient or steady-state. One, two, or three dimensions are available and transport of radionuclides chains is possible.

4. METHOD OF SOLUTION

Finite differencing is used to discretize the partial differential equations in space and time. The user may choose centered or backward spatial differencing, coupled with either central or backward temporal differencing. The matrix equa- tions may be solved iteratively (two line successive-over-relaxa- tion) or directly (special matrix banding and Gaussian elimination).

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

On the CDC7600 in direct solution mode, the maximum number of grid blocks allowed is approximately 1400.

6. TYPICAL RUNNING TIME

Execution time is dependent on problem characteristics. NESC executed each of the 17 sample problems in less than 35 CP seconds on a CDC7600.
NEA-DB executed the 34 test cases included in the distributed package (NESC0973/01) on CDC 7600 in 323 CPU seconds.

7. UNUSUAL FEATURES OF THE PROGRAM

SWIFT can be run in one, two, or three dimensions, with constant pressure of fluid flux boundary conditions, with injection and/or withdrawal walls, with the option to solve individually or collectively the equations of fluid flow, heat flow, brine, or containment displacement, with a choice of finite-difference solution techniques, and with a choice of Cartesian or radial coordinates.

11. MACHINE REQUIREMENTS

70,000 (octal) words of memory are required to compile the SWIFT source. 130,000 (octal) words of small core memory (SCM) and 400,000 (octal) words of large core memory (LCM) are needed to execute the sample problems. SWIFT is designed to permit the user to adjust the machine requirements to problem complexity.

14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS

Object
code may be generated when using the FTN compiler with the Level 414 library which causes an abort at load time because of insufficient available LCM. If this happens, redefine the DIMENSION of the G array and the value of the variable, ICORE, as 131061.
