Starting at GMS version 8.0, GMS supports MODFLOW 2005.

Choosing MODFLOW-2000 or MODFLOW-2005

Choosing to use MODFLOW-2000 or MODFLOW-2005 is done in the MODFLOW Global Options Dialog. At any time you can switch from one to the other.

Changes in MODFLOW-2005

The following list shows changes in MODFLOW-2005 from MODFLOW-2000.

1. SOR1 Solver
  • MODFLOW-2005 no longer supports the SOR1 Solver.
2. PCG2 Solver
  • MODFLOW-2005 replaces the DAMP variable with DAMPPCG and DAMPPCGT variables [1]. These two new variables allow different damping factors to be applied separately to steady-state and transient stress periods.
3. UZF Package
4. LPF package
  • MODFLOW-2005 provides more options for the LPF Package. Pictures below show the LPF package options supported in MODFLOW-2000 vs MODFLOW-2005.

5. PES and PEST
  • PES is not available in MODFLOW 2005. Automated calibration in GMS is handled using PEST.
