ChemFlux is the most powerful and stable finite element mass transport modeling software currently available. ChemFlux is a powerful finite element software package characterized by automatic mesh generation, automatic mesh refinement and automatic time-step refinement. The FlexPDE(tm) solver offers speed and reduction in convergence problems over other similar software packages. Results of benchmark tests run against MT3D confirm the effectiveness of the solver. ChemFlux is able to provide the same level of accuracy as MT3D in solutions dominated by advection while implementing the irregular geometry benefits of the finite element method. ChemFlux can also import groundwater gradients from the powerful SVFlux groundwater modeling package. Our comprehensive documentation will get you modeling quickly!

	ChemFlux 2D represents the next level in contaminant transport modeling. Designed to be simple and effective, the software offers features designed to allow the user to focus on contaminant transport solutions, not convergence problems or difficult mesh creation.

	ChemFlux 3D represents the ultimate in the 3D modeling of saturated and unsaturated contaminant transport flow. Our simple CAD-style input module allows for creation of your model as a series of surfaces and layers. [click for details]

Designed for use by geotechnical/geoenvironmental engineers, hydrogeologists, geological engineers and soil scientists, ChemFlux offers a new level of computing power not currently available. Predicting the movement of contaminant plumes through the processes of advection, diffusion, adsorption and decay is possible.

Automatic mesh refinement advantages in solute transport?
"Steep moving fronts of solute concentration may occur for convective-dispersive transport during water flow in porous media for conditions when the convection term dominates or the concentration moves along in a wave (Finlayson, 1992). Accurate numerical solutions for solute transport involving steep concentration fronts create special requirements for optimum resolution. For convection-dominant transport of solutes in porous media, sharp peaks and valleys of solute concentration, as well as details of the solution controlling transport between nodes after each time step are truncated by interpolation between nodes. Such truncation is the source of all numerical problems in simulations of convective-dispersive solute transport (Yeh, 2000).

Truncation of peaks and valleys is an important cause of peak clipping, numerical spreading, and spurious oscillation. Incorporation of local adaptive grid refinement algorithms in numerical models provides opportunity to enhance the accuracy of numerical approximations by automated adjustment of local spatial resolution for such cases" (Mansell et al., 2002).

The ChemFlux design module provides an elegant and simple user interface. Problem geometry and groundwater gradients may be imported from the SVFlux software. ChemFlux modeling is therefore fast and allows the soil professional to focus on the model and not the method.

"As an engineering tool no other software on the market can match the ability of SVFlux and ChemFlux to explore creative solutions for seepage and contaminant hydrogeology problems"

"The software developed by SoilVision Systems Ltd. for 3D saturated / unsaturated flow is a powerful tool for the analysis and design of reclamation systems for waste rock and mine tailings. Groundwater flow together with fate and transport issues are central to the design of remedial measures. SoilVision has demonstrated the ability to provide 3D solutions for difficult unsaturated flow problems in waste deposits at mine sites that cannot be solved using current software available. I feel that SoilVision offers a key service with respect to the remediation and design of long-term closure systems for mine waste management."
