Take your groundwater modeling to the next level with more power, increased performance and MODFLOW-NWT - the new and improved MODFLOW engine.

• Support for MODFLOW-NWT: MODFLOW-NWT - a new and improved version of MODFLOW - provides improved handling of dry cells resulting from water table fluctuations over multiple model layers. Learn more...

• Leverage the power of multi-core processors: The added parallel processing support for various solvers (PCG, WHS & SAMG) and MT3DMS allows you to take full advantage of your multi-core processors and run simulations significantly faster.

• Improved capacity for larger models: Visual MODFLOW v.2011.1 now supports 64-bit versions of MODFLOW-2000, MODFLOW-2005, MODFLOW-NWT and SEAWAT, providing more power and greater capacity when running large and/or complex simulations.

• Accelerated and more efficient solving performance¹: The new LMG2 interface for the SAMG multigrid solver drastically reduces model run times, especially when dealing with large grids and highly variable conductivity fields. Benchmark tests have shown SAMG to be 100 times faster than the PCG solver and up to twice as fast as the GMG solver. Learn more...

• More options for defining evapotranspiration: Evapotranspiration (EVT) boundary conditions can now be applied to different model layers during the simulation, allowing for more accurate and representative models.

• Extended capabilities for lake boundary conditions: New options for lake boundary conditions allow for better handling of lakes with steep gradients where there is both vertical and horizontal flow between the lake and aquifer. Water budgets for lakes can now be plotted and compared with water budgets from multiple models.
