Advantages of ChemFlux 3D

The ChemFlux modeling software package is not designed to be just another contaminant transport modeling package. It is specifically designed to bring contaminant transport modeling to "the next level". As such, it offers the following significant advantages over currently available contaminant transport 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 - ChemFlux is the only contaminant transport software package worldwide to provide automatic mesh refinement based on any problem variable. For example, mesh refinement can be set to respond to concentration. The mesh will then refine itself appropriately for each time-step and respond automatically to zones at the front of the contaminant plume. The automatic mesh refinement will also automatically relax itself in zones where there is no longer need for mesh density.
• Automatic time-step refinement - ChemFlux also provides automatic time-step refinement for transient contaminant transport 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.
• Increased solution stability - The automatic mesh refinement present in ChemFlux 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 ChemFlux to converge around these critical zones is better than conventional contaminant transport software. The solver used by ChemFlux 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.
• 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.
• Convergence Advantages - ChemFlux has been shown to duplicate the best efforts of of the TVD method in the MT3D software for the solution of the "Advection Only" problem. ChemFlux uses the Galerkin finite element method and avoids the mass-related issues of the TVD method.
• 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.
• Modeling in the Unsaturated Zone - ChemFlux is formulated to handle contaminant flow through the unsaturated (vadose) zone.
• Model Creation Method - ChemFlux imports all problem geometry from models created with the SVFlux contaminant transport software package. All the flexibility of model creation provided by SVFlux is available in ChemFlux.
• Metric and Imperial Units - All developed models may be built and viewed using metric or imperial units.
• Internal Database Of Model Soil Properties - An internal database of soil properties (required for contaminant transport modeling) is maintained by the ChemFlux 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 may be input as boundary conditions.
• Multi-User 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.
