DATA SET 3: BASIC REAL PARAMETERS
Basic real parameters: the real parameters for job flow control. This data
set must be proceeded by a data description line. One record of free format
is required.
-
1. DELT = Initial time step size, (T).
-
2. CHNG = Percentage of change in time step size in each of the subsequent
time increment, (dimensionless in decimal point).
-
3. DELMAX = Maximum value of DELT, (T).
-
4. TMAX = Maximum simulation time, (T).
-
5. TOLA = Steady-state convergence criteria, (L).
-
6. TOLB = Transient-state convergence criteria, (L).
-
7. RHO = Density of water, (M/L**3).
-
8. GRAV = Acceleration of gravity, (L/T**2).
-
9. VISC = Dynamic viscosity of water, (M/L/T).
-
10. W = Time derivative weighting factor;
-
0.5 = Crank-Nicolson central and/or Mid-difference,
-
1.0 = backward difference.
-
11. OME = Iteration parameter for solving the nonlinear matrix equation;
-
0.0 - 1.0 = under-relaxation,
-
1.0 = exact relaxation,
-
1.0 - 2.0 = over-relaxation.
-
12. OMI = Relaxation parameter for solving the linearized matrix equation
point blockwise;
-
0.0 - 1.0 = under relaxation,
-
1.0 = exact relaxation,
-
1.0 - 2.0 = over relaxation.
