The innovative new SVFLUX™WR module combines the leading edge SVOFFICE™ CAD-based 2D/3D model building and visualization interfaces with the groundwater modeling abilities of the FEHM solver developed by Los Alamos National Laboratory (LANL). The software was developed over 20 years as phase one of a collaboration between SoilVision and LANL. The FEHM solver produces fast solutions of highly non-linear models considering unsaturated soil mechanics. Therefore, regional flow models including many pumping wells with complex geometry can be modeled. The solution implements a powerful triangular (2D) and tetrahedral (3D) mesher.

It is often hard to find commercial software that allows you access to the raw data. SVFLUX™ not only gives you access, it allows you to export the raw data in several user defined formats. This feature has been invaluable in my Ph.D. program.”

  • "The software developed by SoilVision Systems Ltd. for 3D saturated / unsaturated flow is a powerful tool for the analysis and design of reclamation systems for waste rock and mine tailings. Groundwater flow together with fate and transport issues are central to the design of remedial measures. SoilVision has demonstrated the ability to provide 3D solutions for difficult unsaturated flow problems in waste deposits at mine sites that cannot be solved using current software available. I feel that SoilVision offers a key service with respect to the remediation and design of long-term closure systems for mine waste management.”

  • 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...
