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 ''SMS | 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]. | ||
