Starting at GMS version 8.0, GMS supports 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.

MODFLOW Global Option Dialog

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

1. 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.
