Advantages of SVHeat 2D

The SVHeat automated geothermal modeling software package is not designed to be just another geothermal modeling package. It is specifically designed to bring geothermal modeling to "the next level". As such, it offers the following significant advantages over currently available geothermal modeling software packages:

• Automatic mesh generation - Fully automatic mesh generation is provided based on problem geometry. The automatic mesh generation allows for simulation of extremely complex problems drawn manually or imported from AutoCAD.
• Automatic mesh refinement - SVHeat is the only seepage software package worldwide to provide automatic mesh refinement based on any problem variable. For example, mesh refinement can be set to respond to head, gradients in the x or y direction, permeabilities in the x or y direction, etc.
• Fully Automatic Time-step Refinement - SVHeat also provides automatic time-step refinement for transient seepage models. The time-step refinement provides an added degree of convergence stability in transient problems. Plots of program variables may be selected at any time-step irregardless of the time-step increment used to obtain a solution.
• Customizable Solutions - This unique feature allows experimental formulations to be tested with no programming effort. For more information on this feature, click here.
• AutoCAD DXF import - SVHeat allows problem geometry to be imported from an AutoCAD DXF file thereby greatly reducing the time required to design a model. The automatic mesh generation automatically adapts to difficult imported geometry.
• Modeling in the Unsaturated Zone - SVHeat is formulated to handle heat flow through the unsaturated (vadose) zone.
• Database Driven - All created models are stored in a database. This allows the user to develop a database of models. Models are organized by project and model type for future reference. All previous models can be used as templates in the creation of future models. The database format is also ideal for multi-user environments. The database file may be installed on a server and multiple users may "plug in" to the same file. All model creation is therefore centralized and available to the entire company.
• Metric and Imperial Units - All developed models may be built and viewed using metric or imperial units.
• Increased solution stability - The automatic mesh refinement present in SVHeat causes the mesh to be refined around critical zones of the solution mesh. There are two benefits of this refinement. (1) The user is able to determine the location of critical zones visually, and, (2) the ability of SVHeat to converge around these critical zones is better than conventional geothermal software. The solver used by SVHeat uses the Galerkin Integral method with a non-linear Newton-Raphson iteration technique with pre-conditioning of the convergence matrix. The pre-conditioning of the convergence matrix significantly improves convergence stability.
• Problem Customization - Models set up by the front end are written in a scripting language (similar to MathCAD ™) prior to being solved by the solver. The models may be modified and/or prior to solution by end-users familiar with the mathematical language. Coupling of models may be performed as well as additional functions or problem variables defined.
• 3D modeling capabilities - SVHeat2D can be upgraded to SVHeat3D. SVHeat3D is similar to SVHeat2D and therefore provides consistency to the end user.
• Flexible boundary conditions - Free form equations may be input as boundary conditions.
• Database functionality - All created models are stored in a database. This allows the user to develop a database of models. Models are organized by project and model type for future reference. All previous models can be used as templates in the creation of future models. The database format is also ideal for multi-user environments. The database file may be installed on a server and multiple users may "plug in" to the same file. All model creation is therefore centralized and available to the entire company.
• Internal database of model soil properties - An internal database of soil properties (required for geothermal modeling) is maintained by the SVHeat software (separate from the SoilVision database). The user therefore has a choice with each new model to either enter new soil properties or pull soil properties from a previous problem.
• Price advantage - SVHeat is designed as high-end geothermal modeling software while not breaking your budget! Email us for our current price list.
