- SVOFFICE™5/WR Water Resources Suite has been developed for hydrogeologists and is centered on the integration of the powerful FEHM finite element solution engine developed by Los Alamos National Laboratory (LANL). The completion of phase one has resulted in the release of SVFLUX™WR which utilizes the front-end/back-end user-friendly interfaces of SVOFFICE™5 to build complex 3D regional numerical models. The SVFLUX™ module is integrated with the SVDESIGNER™, SVSOILS™, and SVSLOPE® modules in the SVOFFICE™5/WR suite. This powerful combination allows hydrogeologists to create complex numerical models and have the calculated pore-water pressures subsequently imported and utilized by geotechnical engineers in a slope stability analysis.
The FEHM solver has been developed extensively by LANL over the past 30 years and represents over 50 man-years of effort. The solver allows stable solution of large highly non-linear unsaturated groundwater models and has been utilized on many government and international projects including analysis of EPA superfund sites.
The collaborative program between SoilVision and LANL links the robust and comprehensive FEHM control volume finite element solver with the easy to use SVOFFICE™ user interface to create a comprehensive numerical modeling package with extensive capabilities in the areas of regional groundwater modeling. The research and development program couples the existing SVOFFICE™ modules with their existing easy to use CAD interface and modular model design to serve as a package capable of greatly speeding model design using the FEHM solver. Models can be created in a matter of hours and then analyzed with the comprehensive FEHM capabilities. The SVOFFICE™ front end allows generation of triangular (2D) or tetrahedral (3D) meshes in full 3D space - multiple nodes per layer and pinch-outs can be modeled. The ACUMESH™ back end visualization provides extensive and state of the art visualization capabilities to the FEHM solver. Extremely large scale models of over a million nodes can be visualized and the results visualized in a simple manner or animated in the ACUMESH™ visualization engine. The purpose of the collaboration is to bring efficiency and speed to the model creation process for a hydrogeological control volume finite element solver proven as one of the most capable in the world.
The use of the FEHM solver developed by Los Alamos National Laboratory (LANL) provides the following advantages to numerical modeling solutions:
- Stable solutions of non-linear unsaturated models with high numbers of nodes
- Ability to utilize supercomputers for high-demand solutions
- Comprehensive modeling of drawdown and recharge for pumping well networks
- Ability to solve regional models with extremely thin lateral layers
The new software package brings an extensive array of new features to the release and makes them easily accessible to end users such that the models can created in solved in a consulting time frame. The following features specifically are able to be analyzed with the FEHM solver:
- 3-dimensional complex geometries with unstructured grids
- Saturated and unsaturated media
- Fully implicit, fully coupled Newton Raphson solution of non-linear equations
- Control volume (CV) and finite element method (FE) methods
Very large 3D numerical models have often been avoided due to the complexities related to solving 3D models with many nodes. The FEHM solver brings its exceptional design based in high end computing platforms to the forefront and allows stable solutions with very complicated 3D numerical models. Therefore, FEHM allows for robust and comprehensive 3D solutions with extreme numbers of nodes to be solved with optimum efficiency.

Time-Tested and Industry Proven
The FEHM solver was utilized on the famous Yucca Mountain nuclear storage project to model the regional groundwater flow to ascertain the ability of the site to accept nuclear waste.
The numerical background of the FEHM computer code can be traced to the early 1970s when it was used to simulate geothermal and hot dry rock reservoirs. The primary use over a number of years was to assist in the understanding of flow fields and mass transport in the saturated and unsaturated zones below the potential Yucca Mountain repository. Today FEHM is used to simulate groundwater and contaminant flow and transport in deep and shallow, fractured and un-fractured porous media throughout the US DOE complex. FEHM has proved to be a valuable asset on a variety of projects of national interest including Environmental Remediation of the Nevada Test Site, the LANL Groundwater Protection Program, geologic CO2 sequestration, Enhanced Geothermal Energy (EGS) programs, Oil and Gas production, Nuclear Waste Isolation, and Arctic Permafrost...
