DATA SET 22: BASIC REAL AND INTEGER PARAMETERS FOR BIOGEOCHEMISTRY CALCULATIONS

One line of unformatted input contains the following 6 variables.

1. OMEGAC = relaxation parameters for iteration:

0 ~ 1 = under-relaxation,

1 = exact relaxation,

1 ~ 2 = over-relaxation.

2. NPCYL = number of cycles allowed for iterating precipitation-dissolution. (Set NPCYL = 1 if precipitation-dissolution is not present in the simulation).
3. NITERC = number of iterations allowed.
4. EPSC = error tolerance for iteration.
5. CNSTRNX = a factor for the constraint on complexed species concentration. No complexed species concentration would yield a total component concentration greater than CNSTRNX times of the input total component concentration.
6. CNSTRNY = a factor for the constraint on adsorbed species concentration. No adsorbed species concentration would yield a total component concentration greater than CNSTRNY times of the input total component concentration.
7. IPIV = option for pivoting for solution of the Newton-Raphson matrix equations.

1 = full pivoting.

2 = partial pivoting.
