SVHEAT™ is designed for the calculation of conductive and convective heat movement in frozen or unfrozen soils. It has the ability to handle building foundations, pipelines, or thermosyphons and the input of detailed climate weather station data to calculate the influence of atmospheric conditions. The impact of climatic conditions can be determined through an advanced snow boundary condition.

Product OverviewProduct Overview

Easy Implementation of Advanced Climate Boundary Conditions

The SVHEAT™ software package continues to be a market-leading thermal analysis package which offers both 2D and 3D analysis. It is applicable to geotechnical, civil, and mining-related engineering projects.

The product can be coupled with SVFLUX™ and/or SVAIRFLOW™ to model complex situations.

SVHEAT™ is designed for the calculation of conductive and convective heat movement in saturated or unsaturated soils. The software implements the ability to handle thermosyphons and the input of detailed climate weather stations data to calculate the influence of atmospheric conditions. Advanced boundary conditions allow the accomodation of the thermally insulating effects of snow on a boundary and is able to calculate geothermal gradients and the movement of freezing fronts. SVHEAT™ allows you to analyze steady-state or transient thermal conduction and

convection models. Convection models may be created by coupling with SVFLUX™. User defined soil properties define the latent heat released or absorbed during the ice-water phase change.

SVHEAT™ is currently being used by universities and consultants around the world. Feel free to contact us for more information.

Key features and enhancements of SVFLUX™:
  • Re-organized Menu: the menu system within the software has been reorganized slightly in a clearer format. Primary functions are organized in a left to right format along the menu.
  • Re-designed Project Manager: the project manager dialog has been redesigned to greatly simplify its usage. It also allows the advanced abilities of model grouping and linking which is particularly useful in large and complex modeling sequences.
  • Fully Integrated 1D / 2D / 3D Geotechnical Suite - performs conductive or convective analysis of problems and coupling of thermal, hydraulic and airflow (THA) processes are possible.
  • Automatic mesh generation and mesh refinement
  • Model both conductive and convective heat flux, in frozen or unfrozen conditions
  • Easy to use - quickly design models based on an intuitive CAD user interface and logical feature layout allowing creation and completion of models in hours or days .. not weeks or months!
  • Climatic interface SVFLUX™ / SVHEAT™ allows entry of detailed climatic data. Implementation of the rigorous Fredlund-Wilson-Penman climatic interface allows calculation of actual evaporation at the ground surface
  • Snow - modeling of the insulating effects of snow is possible with advanced boundary conditions
  • Continuous Innovation - Quick addition of features for our customers. New versions are generated every two - four weeks!
  • World Class support - highly dedicated team with tracking and fast response to all raised issues - typically within 24 - 48 hours.
  • Model customization through a powerful math scripting interface*

* SVHEAT™ uses a math scripting language to solve numerical models. This easy-to-understand script requires no programming skills and allows users to customize our formulations.

Customers and TestimonialsCustomers and Testimonials

With every new piece of software there is always a learning curve. While I was learning to use SVHEAT™, SoilVision was there every step of the way to help me through hurdles I encountered. When I needed a change or an improvement in the software, the development team responded promptly to my requests and made changes with impressive speed. SoilVision's SVHEAT™ has proved itself be an invaluable tool for designing structures in arctic conditions and permafrost soils. Predicting the results of a changed thermal regime allows us to design stable long term structures for our clients. SVHeat's excellent graphical and 3-dimensional output encourages an intuitive understanding of the dynamics involved. I would recommend the SVHEAT™ software and SoilVision's support to anyone.”

Torsten Mayrberger, Ph.D

I do think this type of modeling should be more routinely done and until now there has not been an easy way of doing this. Beyond a few hiccups in setting up the model (mostly lack of CAD software experience on my part) and then the subsequent setting up and understanding of physical properties and units (small learning curve) the model ran and calculated quickly with good visual results. I would have no reservations in recommending SVHEAT™ heat modeling to better understand heat flow into borehole heat exchangers in a residential geothermal installation. This understanding can be applicable to borehole spacing and depth of drilling for any particular ground and aquifers that intersect the boreholes.”

My study required the input of large data including surface temperatures ranging from 350°C to -300°C. The flexibility and versatility in SVHEAT™ allowed me to run thermal simulations with sudden changes in boundary conditions using non-linear material properties.”

Modelling can be time consuming but SVHEAT™ improved our efficiency by allowing us to use AutoCAD™ drawings and automatic mesh generation while managing the input data through a database.”
