GeoStudio 2D Flow includes the following:
AIR/W
AIR/W is a powerful finite element software product for modelling air transfer in mine waste and other porous media. AIR/W can be used to model a range of scenarios, from simple single phase air transfer problems to complex coupled air-water systems.
CTRAN/W
CTRAN/W is a powerful finite element software product for modelling solute and gas transfer in porous media. CTRAN/W can be used to model simple diffusion-dominated systems through to complex advection-dispersion systems with first-order reactions.
SEEP/W
SEEP/W is a powerful finite element software product for modelling groundwater flow in porous media. SEEP/W can model simple saturated steady-state problems or sophisticated saturated/unsaturated transient analyses with atmospheric coupling at the ground surface.
TEMP/W
TEMP/W is a powerful finite element software product for modelling heat transfer and phase change in porous media. TEMP/W can also analyse simple conduction problems to complex surface energy simulations with cyclical freeze-thaw.
CTRAN/W is a finite element software product that can be used to model the movement of contaminants through porous materials such as soil and rock. The comprehensive formulation of CTRAN/W makes it possible to analyze problems varying from simple particle tracking in response to the movement of water, to complex processes involving diffusion, dispersion, adsorption, radioactive decay and density dependencies. You can apply CTRAN/W to the analysis and design of geotechnical, civil, hydrogeological, and mining engineering projects.
CTRAN/W is integrated with SEEP/W and has the same CAD-like interface. The two software products must be used in tandem to analyze contaminant transport. SEEP/W computes the water flow velocity, volumetric water content, and water flux. CTRAN/W uses these parameters to compute the contaminant migration.
Easy to Use
Defining a Contaminant Transport Model
Once you have solved your flow problem with SEEP/W, you can use the graphical tools in CTRAN/W to interactively apply boundary conditions and specify material properties. Conduct a simple particle tracking analysis, or define dispersivity, diffusion, adsorption, decay and density to conduct an advection-dispersion analysis. If you make a mistake, you can correct it using the Undo command.
Viewing the Analysis Results
Once you have solved your contaminant transport problem, CTRAN/W offers many tools for viewing results. Generate contours or x-y plots of any computed parameter, such as concentration, mass, adsorption, dispersion, or Peclet and Courant numbers. Velocity vectors show the flow direction and rate. Examine the contaminant mass in the solid and liquid phases at any location. Transient conditions can be shown by plotting the changing concentration levels over time. Interactively query computed values by clicking on any node, element Gauss region, or flux section. Then export the results into other applications, such as Microsoft Excel or Word, for further analysis or to prepare presentations.
Typical Applications
CTRAN/W can model almost any contaminant transport problem, including:
- • Flow of contaminants from a surface pond
- • Flow of dissolved hydrocarbons
- • Flow of radioactive contaminants
- • Transport through fractured rock
- • Sea-water intrusion into coastal aquifers
- • Brine transport
- • Landfill leachate migration
