FEFLOW and Leapfrog Hydro


The complete tool set for hydrogeological modeling

Joining the powers of the best-in-class geologic and groundwater modeling tools: Easily build detailed geologic models in Leapfrog Hydro and seamlessly transfer them to FEFLOW which can handle your most demanding groundwater simulation tasks. Both Leapfrog Hydro and FEFLOW feature state-of-the-art interactive 3D graphical capabilities.

 



  
If your project requires advanced subsurface-simulation technology combined with highly flexible meshing, then FEFLOW is the answer.


 Leapfrog Hydro provides dynamic, flexible and extremely fast interactive geological modeling incorporating a multitude of data sources—including well logs, sections, GIS data, and more.
 

 Let Leapfrog Hydro build a 3D mesh geometry for you based on the geological model and the imported 2D mesh.
Use the advanced FEFLOW 2D mesh generation options to create an optimal horizontal mesh for the groundwater simulation task at hand.  
Complete initial and boundary conditions and build a groundwater model as complex as required for your application. It is you setting the limits!  
 




Export the 3D model and initial parameters in FEFLOW format.
 





  
Run and calibrate your groundwater model.


Compare model geometry and geological data. You have modified the model geometry in FEFLOW? No problem - use the new FEFLOW layer interfaces to update your hydrogeological model. Even legacy FEFLOW models can be visualized by Leapfrog Hydro!
The combination of Leapfrog hydro and FEFLOW provides you with the most advanced hydrogeological and ground-water modeling tools currently available. Improve your groundwater modeling results now by seamlessly integrating your hydrogeological models!

Speeding and improving the conceptual modelling process


Leapfrog Hydro is a tool for developing and refining 3D geologic models as well as knowledge discovery and numerical analysis within geological systems. The software also interfaces to the FELFOW flow and transport simulator. Leapfrog Hydro is based on the implicit modelling approach. This results in a work flow for the rapid development of geological models. To quote a user: “Having worked with geologic modelling tools since 1990, I find Leapfrog Hydro to be the most innovative, cost effective, and flexible geologic modelling tool I have yet seen. Leapfrog Hydro helped us to quickly solve the most complex geologic modelling challenge we've faced in years.”

Key tools

Leapfrog Hydro is designed for integration in your business processes; so you can directly use data from other tools like:

  • GIS data in vector and raster format
  • Images (georeferencing tools)
  • Borehole logs: lithology, wire-line, et al.
  • Well screen data (e.g. water levels and concentrations)
  • Point data
  • Scanned cross-sections
  • Other geological modelling packages.

Typical example

A typical example of an application is the construction of a geological model for this peninsula. We have a

Roughly 350 borehole logs that cover the site (Figure 1). The geologic situation is dominated by glacial deposits. The goal is to develop a geological model that can be used to address water resource concerns since water quality is threatened from a number of sources.

 

Figure 1: Data at the site. On the left we have the borehole logs, while on the right we can see the processed borehold logs and DC-resistivity data.

The borehole descriptions are regrouped using tools in Leapfrog Hydro, for example coarse and fine sands can be grouped together. Using the geological descriptions and tools in Hydro descriptions can, if necessary, be split up into sub-groups (Figure 2).

Figure 2: The same cross-section through the data set, on the left the processed borehole descriptions and on the right the same borehole data after the main aquifer (light blue) is separated out using the graphical selection tools in Hydro.

Figure 3: Along the cross-section line we see the FEFLOW model sliced and the borehole data.

Transfer to FEFLOW

  • Assign properties
  • Check resolution

Benefits

Leapfrog Software enables a significant improvement modelling through:

  • Productivity: The software aids staff in carrying out routine tasks more rapidly than in traditional work flows as well as speeding up data cleaning and analysis. Training requirements are lower than for competing products.
  • Better analysis: Since time allotted to routine tasks is reduced staff can carry out more analysis resulting in better results. Leapfrog Software is designed to aid in QA/QC. These will give you a market advantage over the competition.

One user told us that the time savings alone on transferring geological models to flow models justified the purchase of Leapfrog Hydro.

A user survey shows that a single seat of Leapfrog Hydro on average is used by 3 staff members. If each staff member can save 25 hours of work a year, the software is paid for. Additionally, product quality can be improved for the same resource allocation for project work.
