Particle tracking for MODFLOW-USG: A demonstration of mod-PATH3DU runs using Visual MODFLOW Flex

2016-11-22T18:26:26+00:00 July 30th, 2014|Categories: Groundwater Modeling, MODFLOW-USG, Visual MODFLOW Flex|Tags: , , |

The new particle tracking program mod-PATH3DU, developed by S.S. Papadopulos & Associates, provides a vital component for interpretation and analysis of MODFLOW-USG groundwater models. This program will be integrated into Visual MODFLOW Flex in a future release. The following images are some of examples of pathline analysis using mod-PATH3DU and UnStructured Grid models (Voronoi and Quad-Based [...]

A logical and flexible approach to creating Quad-Based UnStructured grids using Visual MODFLOW Flex

2016-11-22T18:26:26+00:00 March 25th, 2014|Categories: Groundwater Modeling, MODFLOW-USG, Visual MODFLOW Flex|Tags: , |

MODFLOW-USG gives you the flexibility to focus grid resolution where it counts, using a variety of grid geometries.  As mentioned in an earlier blog post, Quad-Based grids are an attractive option due to their simplicity and rectangular-shaped geometry (using shapes similar to those used in finite difference grids).  This blog article provides a preview of the  [...]

Utilizing layer-dependent discretization to accommodate a wide variety of grid-refinement needs for MODFLOW-USG

2017-03-17T14:48:41+00:00 March 12th, 2014|Categories: Groundwater Modeling, MODFLOW-USG, Visual MODFLOW Flex|Tags: , |

In 2013 Visual MODFLOW Flex demonstrated the power of MODFLOW-USG through the use of Voronoi polygon unstructured grids. By focusing the grid resolution “where it counts”, you can achieve higher accuracy and more efficient run times over structured MODFLOW grids. (See MODFLOW-USG Case Study). Building on the new capabilities of MODFLOW-USG and leveraging the flexibility that [...]

MODFLOW-USG Online Course Reaches Record High Enrollment

2016-10-25T20:56:01+00:00 December 18th, 2013|Categories: Events, MODFLOW-USG, Training, Visual MODFLOW Flex|

Waterloo Hydrogeologic hosted two successful online training courses focused on groundwater modeling with MODFLOW-USG on December 11th and 12th. This course followed the release of Visual MODFLOW Flex 2014.1 which introduces support for MODFLOW-USG - a new version of the MODFLOW groundwater flow program that uses unstructured grids. The course content focused on MODFLOW-USG theory including details [...]

Case Study: MODFLOW-USG Yields 90% Reduction in Run Times for Regional Groundwater Model

2016-11-22T18:26:29+00:00 November 12th, 2013|Categories: Groundwater Modeling, MODFLOW-USG, Visual MODFLOW Flex|Tags: |

One of the main benefits of MODFLOW-USG is that it is capable of achieving a high level of accuracy, with much fewer grid cells than what would be needed with MODFLOW-2005. In order to quantify the performance gains, we ran a benchmark test that compared the run time of MODFLOW-USG to the run time of MODFLOW-2005 [...]

Visual MODFLOW Flex 2014.1 Released With Support for MODFLOW-USG (Unstructured Grids)

2016-11-22T18:26:29+00:00 November 11th, 2013|Categories: Events, Groundwater Modeling, MODFLOW-USG, Visual MODFLOW Flex|Tags: |

Waterloo Hydrogeologic is pleased to announce the release of Visual MODFLOW Flex 2014.1 which provides support for MODFLOW-USG - a new finite volume version of the MODFLOW groundwater flow program that uses flexible and efficient unstructured grids to deliver increased accuracy and reduced simulation runtimes. Visual MODFLOW Flex 2014.1 is unique in that it permits users to [...]
