Advantages of SVAirFlow 2D

The SVAirFlow automated soil vapor extraction modeling software package is not designed to be just another SVE package. It is specifically designed to bring soil vapor extraction modeling to "the next level". As such, it offers the following significant advantages over currently available SVE 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 - SVAirFlow is the only air-flow software package worldwide to provide automatic mesh refinement based on any problem variable. For example, mesh refinement can be set to respond to pressure gradients in the x or y direction, or any other problem variable.
• AutoCAD DXF import - SVAirFlow 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.
• 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.
• Increased solution stability - The automatic mesh refinement present in SVAirFlow 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 SVAirFlow to converge around these critical zones is better than conventional air-flow software. The solver used by SVAirFlow 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 - SVAirFlow2D can be upgraded to SVAirFlow3D. SVAirFlow3D is similar to SVAirFlow2D and therefore provides consistency to the end user.
• Metric and Imperial Units - All developed models may be built and viewed using metric or imperial units.
• Multi-User 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 soil vapor extraction modeling) is maintained by the SVAirFlow 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.
• Flexible Boundary Conditions - Free form equations or tabled precipitation data may be input as boundary conditions.
• Price advantage - SVAirFlow is designed as high-end soil vapor extraction modeling software while not breaking your budget! Click here for current pricing!
