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. Switch from one to the other at any time.
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
- MODFLOW-2005 added support for the Unsaturated Zone Flow (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.
