MODFLOW and MORE 2013

We enjoyed seeing many of you at this year's MODFLOW and MORE 2013: TRANSLATING SCIENCE INTO PRACTICE conference. We had a booth, a couple of posters, and a couple of presentations this year. One poster showed MODFLOW-USG refined grids of different types. The other poster was on MODFLOW Server (images below). Dr. Norm Jones gave a very interesting presentation on Monday on his paper entitled Debating the Long-Term Impact of the Southern Nevada Pumping Project based on consulting work done at Aquaveo. One of Norm's graduate students, Scott Christensen presented on Wednesday on his paper entitled A web-based groundwater mapping and visualization tool using Google Earth which is based on work done partly at Aquaveo and partly at BYU.

Isosurface Transparency

For some time GMS has included the ability to have transparent surfaces and transparent contours. These transparent surfaces can come from a TIN, Solid, Cross Section, Mesh, or Grid. The transparency for these surfaces is controlled by adjusting the transparency field in the Material Properties dialog. For contours, the transparency is controlled in the Contour Options dialog.

One of the new features in GMS 9.1 is the addition of transparency for iso-surfaces. The transparency of individual iso-surfaces can be controlled in the Iso-surfaces Options. Below we show the dialog and some iso-surfaces with and without transparency.

June 2013 Sprint

• Fixed 6 bugs
• Fixed problems with the new "Copy to Coverage" command
• Updated help links to wiki pages and added automated tests to report when these get out of date
• Good progress on improving MODFLOW native text output
• Good progress on open sourcing MODFLOW changes
• Overhauled MT3D Basic Package dialog to make setting starting concentrations much easier
• Project-on-the-fly: made new objects get assigned the display projection
• Sped up test coverage analysis
• Started work on FEFLOW mesh import/export
• MODFLOW-LGR progress
• MODFLOW-USG progress

MODFLOW-LGR

The MODFLOW-LGR interface in GMS is almost done. Here are a couple of images showing a nested child grid in plan view and front view.

MODFLOW-USG Progress

The GMS development team has been working on implementing MODFLOW-USG since the documentation was released on May 3, 2013. We have been making good progress. One of the items related to MODFLOW-USG is the ability to work with unstructured grids. The figures below show some of the grids that we have generated with the development version of GMS. We used the same conceptual model and generated a 3D finite element mesh, a 3D structured Grid, and 3D unstructured grids.

 We will be at the MODFLOW and more 2013 conference this next week. Come by our booth to learn more about new developments in GMS with MODFLOW-USG. We will also have a couple of posters that we are presenting.

GMS Training, Olten, Switzerland

Members of the GMS training team recently completed an onsite training class in Olten, Switzerland from April 22-24. It was an intense 3 day training experience. The small class size allowed the students to be very engaged and learn a lot of material in a short period of time. The day following the training was spent working on the client's groundwater modeling project and applying the principles learned in the training. This type of onsite training is available to clients worldwide at very reasonable price. If you are interested in onsite training, including help with your modeling project, contact training@aquaveo.com.
