GMS Training - San Luis Potosi, Mexico

By alemon on July 1, 2014
Dr Willis Weight of Carol College and Alan Lemon, from the GMS development team, recently taught Groundwater Flow and Transport using GMS to a class of 40 participants. The class was hosted at Instituto Potosino de Investigación Científica y Tecnológica (San Luis Potosi Institute of Scientific Research and Technology). Thank you to all of the participants in the class. We worked very hard for 5 days and the participants were very positive about their learning experience. We would also like to thank our friends at Ecoterra for organizing the class and hosting us.

MODFLOW-USG Training - Philadelphia

By alemon on July 1, 2014
The GMS team recently completed a MODFLOW-USG training course in Philadelphia. Thank you to Dr. Laura Toran for hosting us at Temple University. Alan Lemon, from the GMS development team, and Sorab Panday, principal MODFLOW-USG author, taught the class. The 2 day class was filled with theory and hands on applications with MODFLOW-USG. Course participants were excited to see the new types of grids that can be used with MODFLOW-USG. GMS has many flexible options for creating unstructured grids that make using MODFLOW-USG as easy as using traditional MODFLOW.

New plot axes in GMS 10.0

By mkennard@aquaveo.com on June 18, 2014
The Plot Axes have been overhauled in GMS 10.0. The new axes automatically turn on and off as you rotate the view so that your view is never obscured. The options in the dialog are also much simpler.

GMS 10.0 - Updated Model Checker

By alemon on May 7, 2014

The model checker has been a feature of GMS from the beginning. The purpose of the model checker is to analyze the input data currently defined for a model simulation and report any obvious errors or potential problems. Running the Model Checker successfully does not guarantee that a solution will be correct. It simply serves as an initial check on the input data and can save a considerable amount of time that would otherwise be lost tracking down input errors.

In version 10 the model checker has been updated to make reading its results much easier (see the images below). If GMS does not find any obvious errors or warnings then a message highlighted in Green will appear at the top of the dialog letting you know that the input data is free from obvious errors. If your model contains warnings then a Yellow highlighted message will appear at the top of the dialog telling you that warnings were detected. Then as you scroll through the model checker output the warnings will be highlighted in Yellow. Finally, if your model has errors then a message highlighted in Red appears at the top of the dialog and as you scroll through the output the errors will be highlighted in Red. While these features may not be technological breakthroughs they make using the model checker even easier than previous version of GMS.

MODFLOW-USG Complex Stratigraphy

By alemon on April 29, 2014

MODFLOW–USG (for UnStructured Grid), was developed to support a wide variety of structured and unstructured grid types, including nested grids and grids based on prismatic triangles, rectangles, hexagons, and other cell shapes. Flexibility in grid design can be used to focus resolution along rivers and around wells, for example, or to subdiscretize individual layers to better represent hydrostratigraphic units.

MODFLOW-USG’s subdiscretization capability to better represent hydrostratigraphic units is an extremely powerful feature. Traditional MODFLOW requires that grid layers be continuous throughout the model domain even if the particular stratigraphic unit ends or pinches out.

Complex unstructured grids can be created in GMS by using the horizons approach.

There is a new video on the aquaveo youtube channel that highlights this feature. There is also a new tutorial that explains the various options associated with this feature.
