3. DESCRIPTION OF PROGRAM OR FUNCTION

FEMWATER,BLT is used to model release and transport of contaminants from wastes stored in metallic containers in saturated or unsaturated soil systems including low- level waste disposal sites. Both programs provide two-dimensional, time-dependent, finite-element analyses. FEMWATER calculates water velocity, moisture content, and pressure head in unsaturated/ saturated porous media. BLT, a modification of the FEMWATER code, predicts container degradation, waste form leaching, and radionuclide migration in unsaturated porous media.

4. METHOD OF SOLUTION

FEMWATER and BLT perform two-dimensional time-  dependent analyses using the finite element method. Nonlinearities in the unsaturated flow equations are handled through Picard iteration. The transport equations in BLT are linear, and Gaussian elimination is used to solve the matrix equations.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Maxima of -
   528 finite elements (FEMWATER)
   595 nodal points (FEMWATER)
   225 finite elements (BLT)
   252 nodal points (BLT)
   100 waste-containing elements
    20 different waste types
These limits may be changed by redimensioning the appropriate arrays.

6. TYPICAL RUNNING TIME

Execution time for FEMWATER varies depending  on the number of iterations required to converge the solution. For a typical problem with approximately 500 nodal points, execution time  to calculate the steady-state flow pattern is about 20 CPU minutes on an IBM PC/AT with a coprocessor. For 225 nodal points, BLT execution time is typically about 1.3 CPU minutes per time step. NESC executed the FEMWATER sample problem in approximately 7.5 CPU minutes and the BLT sample problem in approximately 37 CPU minutes on an IBM PS/2 model 70 with a coprocessor.
