SVFLUX™WR is designed for hydrogeologists who want to perform large-scale saturated/unsaturated regional flow modeling. This software was developed as a joint effort between SoilVision and Los Alamos National Labs (LANL). This groundwater seepage application makes use of the advanced FEHM solver to perform the analysis. FEHM code was developed as an advanced finite element solver and came to be after over 50 man-years invested. It has been utilized on many EPA superfund sites. The SVFLUX™WR module allows hydrogeologists to solve models at expanded levels like never before.


Product OverviewProduct Overview

Large-Scale Hydrogeological Groundwater Flow Models

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 Labs (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 pumpling wells with complex geometry can be modeled. The solution implements a powerful triangular (2D) and tetrahedral (3D) mesher.

Solutions can be visualized through the polished ACUMESH™ back-end visualization software.

SVFLUX™WR therefore allows hydrogeologists to quickly unlock the power of the FEHM solver through a fresh and streamlined CAD user interface. Large and complex modeling problems can be set up quickly and efficiently.

We are ready to release the SVFLUX™WR beta for testing and review. If you are a hydrogeologist with an interest in performing large-scale groundwater flow analysis utilizing the proven FEHM solver, then we invite you to apply as a beta-tester today. Applications to beta-test the software may be found here!

FEHM SolverFEHM Solver

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...READ MORE.

Top 10 Reasons to Purchase SVOFFICE 5

The investment in geotechnical / hydrogeological software is an important decision for most consulting firms. Software must perform well and yield results in a limited timeframe such that reports can be completed on time and under budget. We recognize this at SoilVision Systems Ltd. and and have worked hard over the past number of years to provide software which is both easy to use and technologically advanced. We believe that the current SVOFFICE™5/WR software product is the best software suite currently available for geotechnical and hydrogeological applications. Listed below are a few of the reasons why your firm would benefit from our software from the perspective of a manager.

1. 3D Modeling Solutions
  • Modeling of systems which are not adequately represented by a simplified 2D cross section may be accomplished in full 3D. Examples include regional flow, levee analysis, and planar geometry.
