ChemFlux
release!
SoilVision
Systems Ltd. is proud to announce the release
of the ChemFlux contaminant transport finite
element software. ChemFlux represents the current
state-of-the-art in contaminant transport modeling
software. Modeling of water soluble contaminant
is both simple and powerful.
With
features such as automatic mesh generation and
refinement in both 2D and 3D as well as advanced
convergence methods, ChemFlux provides fast
and accurate solutions. Modeling time can be
reduced by up to 80% over currently available
software packages. Benchmarked solutions comparing
the results to MT3D confirm the power of ChemFlux.

SoilVision
Systems Ltd. is proud to announce the upcoming release
of the SVHeat software package. The SVHeat software
package offers 2D and 3D finite element solutions
to geothermal problems in saturated and unsaturated
soils. SVHeat will offer the following general features

Frozen
or unfrozen analysis
Model
heat movement using an unlimited number of soil
regions
Model
heat movement in the saturated or unsaturated zones
Import
groundwater volumetric water contents from SVFlux
Volumetric
heat capacity represented as a constant or by the
Newman equation
Temperature
or gradient boundary conditions may be represented
as constants or free-form equations
Input
3D problems as complex surfaces and layers
In
addition to a stalwart group of features the following
contributions make SVHeat a state-of-the-art package.
model heat transfer in unsaturated soils when coupled
with SVFlux
improved model convergence and stability with preconditioning
of the convergence matrix
automatic mesh refinement
automatically identifies critical zones of the problems
and refines the mesh accordingly
3D model creation
Beta
Testing Program
SoilVision Systems Ltd. is currently taking applications
for beta testers of the SVHeat software package. A
limited number of beta testers will be provided with
a FREE beta version of the SVHeat software. We are
particularly looking for comparisons to existing software
packages or applications to real-world problems. If
you are interested in becoming a beta tester, please
submit your contact information in the form provided
here.
An
area of seepage modeling that has been particularly challenging
is the representation of geomembranes in a seepage modeling
problem. The geomembrane represents a relatively thin and
almost impermeable layer in typical problems. The mesh is
almost impossible to create manually due to the large change
in permeability over a very small spacial distance. The
mesh must be altered from a relatively large element size
to an extremely small element size next to the geomembrane
to allow for a solution while minimizing convergence problems.
Automatic
mesh generation is ideal for the solution of seepage problems
involving geomembranes. As the automatic mesh refinement
algorithm is based on relative error of the partial differential
equation the routine will automatically sense areas of high
flux differentials and refine the mesh appropriately. An
example of this refinement in a typical seepage problem
may be seen in the adjacent figure.
It
can be seen that the mesh refinement in SVFlux refines to
an extremely dense mesh. Solution of this problem without
mesh generation and refinement would be impossible. With
mesh refinement, however, the necessary density is achieved
while using a modest amount of computer resources.
