GWB 2023 Professional

I love this new GWB. An X1t script that took 40 minutes to complete on my 12-core desktop now runs in 2.5 minutes. Amazing.

Race car imageThe Professional edition of The Geochemist's Workbench® 2023 is the complete suite of tools to meet every practicing geochemist's needs.

GWB Pro is your choice for computing phase diagrams and modeling reactive transport. One-dimensional and two-dimensional simulations of reactive transport in single and dual-porosity media, including bioreaction, stable isotopes, and migrating colloids, are a snap. Then animate your results and create video clips with a few clicks.

GWB Pro's advanced algorithms and multithreaded design make it ideal for simulating the fate and transport of contaminants in flowing ground and surface water.

In addition to reactive transport, GWB Pro models kinetic and equilibrium reaction in multicomponent systems, calculates Eh-pH and activity diagrams, and creates a spectrum of specialty plots. You can balance reactions, calculate equilibrium constants, and create powerful geochemical spreadsheets.

ChemPlugin

Drainage basins The amazing ChemPlugin self-linking software object is included with your GWB 2023 Professional subscription at no extra cost.

Use ChemPlugin to quickly, easily, and reliably contruct full-featured reactive and bio-reactive transport models in any configuration. Or, repurpose code from an existing flow model into a powerful reactive transport simulator.

ChemPlugin's sleek API comes with bindings for Python, C++, and Fortran; or readily adapt the SDK to your preferred development environment.

Mass and heat transport

Programs X1t and X2t model reactive transport in one and two dimensions. The models account for:

  • Advection, dispersion, and diffusion
  • Uniform or heterogeneous medium properties
  • Dual porosity (stagnant zone) effects
  • Producing and injecting wells
  • Heat transfer by advection and conduction
  • Internal solute sources and sinks
  • Steady and transient internal heat sources

Phase diagrams

Program Phase2 in GWB Pro is the ultimate tool for calculating phase diagrams, whether simple or complex:

  • Stability of aqueous species, minerals, and gases
  • “True” Eh-pH and activity diagrams
  • Isothermal or polythermal sections
  • Equilibrium and kinetic chemical systems
  • Isotope fractionation
  • Predominance and phase assemblage maps
  • Cross-sectional plots of mass distribution

Equilibrium and kinetic reactions

X1t and X2t can incorporate any combination of equilibrium and kinetic reactions:

  • Mineral, end member precipitation and dissolution
  • Gas transfer
  • Complexation and dissociation
  • Sorption and desorption
  • Redox transformation
  • Catalysis and enzymes

Mobile colloids

Migrating colloids are a critical vector for transport of radionuclides, heavy metals, and other contaminants. The GWB handles them with ease:

  • Any complexing surface can form a colloid
  • The colloid and its surface complexes migrate by advection and dispersion
  • Colloid mobility may vary in time and space, according to a user-supplied function

Bioreactive transport

Models can account for reactions catalyzed by microbial activity:

  • Pure culture and mixed communities
  • Population growth and decay
  • Thermodynamic effects
  • Kinetic rate laws of any form

Stagnant zones

GWB Pro is built from the ground up for dual porosity modeling:

  • Each nodal block divided into free-flowing and stagnant fractions
  • You specify the geometry and characteristic dimensions of the stagnant zones
  • The apps account for species diffusion and heat conduction into and out of the stagnant zones

Stable isotope transport

Reactive transport programs X1t and X2t model stable isotope transport, accounting for the isotopic effects of:

  • Advective, dispersive, and diffusive transport
  • Mineral dissolution and precipitation
  • Gas dissolution and effervescence
  • Sorption and surface complexation
  • Equilibrium and kinetic reactions

Graphics and animation

Program Xtplot renders your reactive transport results.

P2plot displays the results of Phase2 calculations.

  • Phase assemblage and “true” predominance plots
  • Cross-sectional diagrams
