The SSOR package is one of the [[GMS:MODFLOW Packages Supported in GMS#Solver Packages|solver packages]] for MODFLOW supported by GMS. The SOR solver only uses a head change convergence criterion and may result in significant volume budget error. | The SSOR package is one of the [[GMS:MODFLOW Packages Supported in GMS#Solver Packages|solver packages]] for MODFLOW supported by GMS.

; Head change criterion for convergance : 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. | |||
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. | |||
; Print out interval : 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. | |||
