The SVHEAT™WR software package is a market-leading geothermal analysis package which offers both 2D and 3D analysis. It is applicable to hydrogeological and mining-related engineering projects.

SVHEAT™WR is designed for the calculation of conductive and convective heat movement in saturated or unsaturated soils. The software implements the ability to handle water-vapor geothermal multi-phase flow and phase change with boiling and condensing. Advanced boundary conditions allow the accommodation of the injection or withdrawal of heat and fluids. SVHEAT™WR allows you to analyze steady-state or transient thermal conduction and convection models. Convection flow models may be created by coupling with SVFLUX™WR.

We are ready to release the SVHEAT™WR beta for testing and review. If you are a hydrogeologist with an interest in running conductive and convective heat movement analysis, then we invite you to apply as a beta-tester today. Applications to beta-test the software may be found here!

What Our Customers Say

  • "We have allowed our students the choice of using multiple Geotechnical software suites in our Dam Design and other Geotechnical courses. Our students consistently gravitate towards SoilVision software as being the most modern and user-friendly."

  • "I've been a geotechnical engineer for more than 25 years and SoilVision has the best tech support I have ever worked with. I truly appreciate their patience and help over the past year."

  • "Peter Brett Associates have been looking to update our existing slope stability software over the last year. After extensive research and trials, SVSLOPE® developed by SoilVision Systems Ltd. was found to meet all our existing and future design requirements. Its ease of use for modeling simple as well as complex geological and geometrical problems was a critical factor in our assessment as well as the incorporation of design to the Eurocodes. Their customer support has been faultless and their willingness to develop the software to meet our own specific design requirements is a most gratifying added bonus."

    "We love the fact that SVSLOPE® is part of an integrated suite of software and that, if required, 3D analysis can be undertaken. We would recommend this product to other geotechnical consulting firms."

  • "We have been using SVSLOPE® and SVFlux™ for the past year and have found them to be efficient and productive engineering tools which have allowed us to offer our services in an efficient manner. The capability of automated increased discretization of the mesh is an absolute benefit to our modeling, reducing time and effort. We have found the software quick and easy for our engineers to train and utilize. I would recommend this product to other geotechnical consulting firms."

  • "The software is well documented and comes with number of useful example models. We were able to quickly begin creating models after a short review of the user interface and going through the available on-line webinars. The software offers solid benefits of less conservatism and the ability to model real geometry."

  • "This new software for stability analysis includes a number of state-of-the-art options for probabilistic slope stability analysis. This feature, combined with comprehensive deterministic analyses, will provide new opportunities to build confidence in the results of a site-specific analysis.”

  • "I'm excited to see the release of this new and innovative product. I look forward to and encourage the application of this software on additional geotechnical projects.”

  • "In consulting engineering practice, I am increasingly made aware of the important and beneficial role that modeling the unsaturated soil zone can play in providing the client with the best possible engineered solution. The SoilVision software has made it possible to readily estimate and incorporate unsaturated soil properties into the modeling of saturated-unsaturated soil systems.”

  • 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.

  • 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/GE software product is the best software suite currently available for geotechnical and hydrogeological applications.
