The SSOR package is one of four solver packages for MODFLOW supported by GMS. The others include the LMG (default), PCG2, and SIP packages. The SOR solver only uses a head change convergence criterion and may result in significant volume budget error.
This value is the maximum solver iterations per timestep. The default value is 50.
This value is usually between 1.0 and 2.0
When the maximum absolute value of head change from all cells during an interation is less than or equal to the head change criterion, solver iteration stops.
The maximum absolute head change is printed for each iteration of a time step whenever the time step is an even multiple of the print out interval. The printout also occurs at the end of each stress period regardless of the print out interval.
