Leapfrog Hydro 2.0 facilitates quality water flow modelling


Leapfrog Hydro 2.0 facilitates quality water flow modelling

CHRISTCHURCH, New Zealand, 26 June 2013
- ARANZ Geo Limited, developer of 3D geological modelling software Leapfrog® Hydro, announced today the release of Leapfrog Hydro 2.0. The major release further improves the interface to specialist flow modelling software MODFLOW and FEFLOW, ensuring streamlined workflows for rapid understanding and resolution of complex water problems.

Increase confidence & reduce risk
Shaun Maloney, CEO of ARANZ Geo, says “Quality flow modelling starts with great geological modelling. With Leapfrog Hydro 2.0 geological understanding can be quickly and seamlessly turned into quality flow models, radically simplifying and streamlining workflows. This not only means efficiency gains, but gives hydrogeologists more time to look at multiple hypotheses and increase confidence in their modelling.”

Refining decision making
Leapfrog Hydro 2.0 has a powerful new engine for exceptionally fast construction of interlocking geological models. Hydrogeologists can explore different hypotheses in rapid succession, leading to confident decision making. Dynamic modelling means models are up-to-date with the latest information, so models readily reflect new sampling data and decisions are timely. The latest cutting edge 3D graphics means visualisation is exceptionally clear, giving users a better understanding of the models and facilitating communication to a wide audience.

Competitive edge

Maloney continues, “The typical Leapfrog Hydro user is an international consulting company handling a diverse range of client projects. They often rely on Leapfrog Hydro for contaminated site management, but it’s also used for allocating groundwater. More recently Leapfrog Hydro has been used for modelling salt water intrusion.
“With significant improvements to the flow modelling interface, Leapfrog Hydro 2.0 effectively covers the whole groundwater modelling workflow. This gives our customers a competitive edge as they can rapidly arrive at more robust models that accelerate projects, reduce risk exposure and save costs; all essential in today’s competitive markets.”


Geological models can be used to create both MODFLOW and FEFLOW models. Gridding accurately reflects the geological features and can be parameterized directly from the geology (e.g., voids from tunnels or caves). Users can easily import MODFLOW and FEFLOW legacy models for comparison to current data and to construct dynamic models.

Output visualisation

Leapfrog Hydro is the ideal tool for interpreting results of simulation runs as MODFLOW transient simulation outputs can easily be visualised in high definition 3D. These advanced graphical capabilities improve and speed up understanding and ease communication. The software is now compatible with OpenGL3.0 for higher frame-rates and more realistic rendering with transparencies.


Even large numerical datasets such as sub-surface contamination levels can be analysed and visualised using Leapfrog Hydro’s powerful dynamic interpolation engine.

ARANZ Geo’s Senior Software Engineer John Good says “Effectively managing groundwater requires a good understanding of the local geology. Enhancements to Leapfrog Hydro’s interface with flow modelling software means users can benefit from significant integration and provide better, more reliable modelling results in less time. Leapfrog Hydro 2.0 effectively bridges the gap between geological and groundwater modelling software.”

ARANZ Geo has a global alliance with DHI, the developer of FEFLOW. As part of this partnership, Leapfrog Hydro is also available worldwide through DHI offices.
