The GMG package is one of four [[GMS:MODFLOW Packages Supported in GMS#Solver Packages|solver packages]] for MODFLOW supported by GMS. The GMG solver is an iterative solver based on a multi-grid approach.
Parameters include:
* Inner convergence residual (RCLOSE)
* Maximum inner iterations (IITER)
* Outer convergence residual (HCLOSE)
* Maximum outer iterations (MAXITER)
* Damping parameter (DAMP)
* Damping option (IADAMP)
* Maximum damping (DUP)
* Minimum damping (DLOW)
* Maximum head change (CHGLIMIT)
* Output flag (IOUTGMG)
* Maximum head output (IUNITMHC)
* Multi-grid preconditioner smoothing (ISM)
* Multi-grid preconditioner coarsening (ISC)
* Relocation parameter (RELAX)

The GMG package is one of four solver packages for MODFLOW supported by GMS. The GMG solver is an iterative solver based on a multi-grid approach.

Parameters include:

  • Inner convergence residual (RCLOSE)
  • Maximum inner iterations (IITER)
  • Outer convergence residual (HCLOSE)
  • Maximum outer iterations (MAXITER)
  • Damping parameter (DAMP)
  • Damping option (IADAMP)
  • Maximum damping (DUP)
  • Minimum damping (DLOW)
  • Maximum head change (CHGLIMIT)
  • Output flag (IOUTGMG)
  • Maximum head output (IUNITMHC)
  • Multi-grid preconditioner smoothing (ISM)
  • Multi-grid preconditioner coarsening (ISC)
  • Relocation parameter (RELAX)
