TT CARD: Crank-Nicholson Theta
Card Description: Used to specify a value for THETA in the Crank-Nicholson
0, C 1-2
Card group identifier.
A value between zero and one (0.66 is
Default = 0.5 This produces the most sensitive
model response but often causes oscillations in
NOTE: A value of 0.66 is recommended, but variations from 0.5 (equal
weighting of this time - step and the previous time - step) to l.0 (no influence from
the previous time - step) are permitted. A higher value of Theta produces results that
are more stable but numerical (artificial) dispersion of sediment is increased.
