Density, viscosity and enthalpy of different phases are automatically calculated at each Newton-Raphson iteration based on the thermodynamics functions of temperature and pressure
Control volume (CV) and finite element (FE) methods:
Provide stabilized numerical solutions for unsteady problems
Readily handle very complex geometry
2D and 3D solutions
Easily generate 3D models from 2D cross-sections, or slice 3D models into 2D cross-sections
Import soil properties from the SVSOILS™ database of over 6200 soils
Surface Mesh Support: The new 3D solution offers support for both surface meshes and grids. Surface mesh support allows models of higher complexity to be produced. Models may be based on geometry obtained from SVDESIGNER™ or from other geological modeling packages such as Vulcan, Minesite, GoCAD or Surpac.
Fully automatic unstructured (2D triangular and 3D tetrahedral) and structured (2D quadrilateral) mesh generation and manual mesh refinement:
The new SVHEAT™WR module introduces a new automatic mesh generation algorithm for increased user control over the mesh
We introduced the new Selective Mesh Refinement function to allow the user to manually select specific areas of interest, key zones or along critical boundaries for more targeted refinement processing
Stunning visualization of results
Easy to use and simplified CAD-based user interface:
A clearly organized menu system with left to right arrangement of primary functions
Allows for the rapid creation of models
The new 3D CAD graphics engine provides measurably faster overall operation
SVDESIGNER™ Conceptual Modeling Software Package: This brand new software program is tightly integrated with SVOFFICE™5/WR and allows for the representation and manipulation of complex 3D geometry and takes 3D modeling to a whole new level.
SVOFFICE™5 Manager: the Manager dialog has been redesigned to greatly simplify its usage. Models can easily be grouped by project and stored anywhere on the user’s disk drive.
Extensive QAQC program
World Class Support: Highly dedicated team with tracking and fast response to raised issues - typically within 24 - 48 hours
Geothermal Modeling and Analysis Ideally Suited for Hydrogeology
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.

Simulate heat conduction and convection in porous media
Model high-temperature and high-pressure geothermal systems
Model borehole heat exchangers
FEHM 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.
