The Sparse Matrix Solver (SMS) Package is the solver | The Sparse Matrix Solver (SMS) Package is the only solver package compatible with [[GMS:MODFLOW-USG|MODFLOW-USG]] and is not compatible with other MODFLOW models. | ||
The ''MODFLOW SMS Solver'' dialog has the following options: | |||
*''Comments (Text)'' – Places a comment in the solver. | |||
* Max head change between outer iterations (L)(HCLOSE) | * Max head change between outer iterations (L)(HCLOSE) | ||
* Max head change between inner iterations (L)( | * Max head change between inner iterations (L)(HICLOSE) | ||
* Max number of outer nonlinear iterations for problem (MXITER) | * Max number of outer nonlinear iterations for problem (MXITER) | ||
* Max number of inner linear iterations for problem (ITER1) | * Max number of inner linear iterations for problem (ITER1) | ||

More information regarding inputs to the SMS package can be found in the MODFLOW-USG documentation at [http://pubs.usgs.gov/tm/06/a45/pdf/tm6-A45.pdf pubs.usgs.gov]. | |||
The SMS package, when used with GMS, also includes the option of using the [[GMS:LMG Package|SAMG or LMG]] within the SMS package. This option is selected under the ''Linear matrix solver (LINMETH)'' option in the ''MODFLOW SMS Solver'' dialog. | |||
