Info

– B.10 – #2 dummy text A string of any number of characters; this line is not read. #3 i, j, x, y, zb, zs 2 integer numbers: the (i,j) cell indices and 4 real numbers: the (x, y) coordinates of the bed vertices, and the bed (zb) and the surface (zs) coordinates. The above input is to be repeated according to the number of vertices, (nx,ny), of the computational domain. B.3 Source code The source code of the program consists of 6 program files and 11 variable-declaration files: 1. ke.f — the main program. 2. keflow.f — the flow model. 3. keturb.f — the k-� model. 4. keinit.f — the initialization routines. 5. keread.f — the routines that read the data from or write the results to a file. 6. kegeom.f — the routines that construct the geometry of the computational domain.� 7. ke_bound.inc — variable declarations: boundary conditions. 8. ke_calcon.inc — variable declarations: computational control-parameters.� 9. ke_coef.inc — variable declarations: variable coefficients.� 10. ke_geo.inc — variable declarations: geometry. 11. ke_grad.inc — variable declarations: gradients.� 12. ke_index.inc — variable declarations: cell indices.� 13. ke_logic.inc — variable declarations: logical variables.� 14. ke_param.inc — variable declarations: space (memory) allocations.� 15. ke_varflo.inc — variable declarations: flow variables.� 16. ke_varold.inc — variable declarations: variables at the n time level.� 17. ke_vartur.inc — variable declarations: k-� variables.� The program is written in the FORTRAN77 language and is suited for the MPW Absoft Version 6.2 compiler. The print out of all files is given in the next pages. The files can also be found in the accompanying CD.
