The SIP (Strongly Implicit Package) solver package is one of the solver packages for MODFLOW supported by GMS.
Maximum Iterations Per Time Step
This value is the maximum number of times through the iteration loop in one time step in an attempt solve the system of finite-difference equations.
Number of Iteration Parameters
Five variables are generally sufficient.
Acceleration Parameter
This value must be greater than zero and is usually 1.0.
Head Change Criterion for Convergence
When the maximum absolute value of head change from all cells during an iteration 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.
Iteration Parameter Seed
These options control the seed for calculating iteration variables. Either specify the seed yourself or have MODFLOW calculate it.
Reset
This button will change all options to the default state.
