New Technology for Smarter and Easier Groundwater Modeling

Adaptive Groundwater is a software program which uses highly-scalable, three-dimensional numerical code for high-resolution simulation of groundwater flow and solute transport problems. Dynamic adaptive mesh refinement (AMR) and multi-threading are used to automatically generate unstructured grids to handle multiple scales of flow and transport processes.

This is done by translating and adding/ removing telescoping levels of progressively finer subgrids during simulation.

With Adaptive Groundwater you can:

  • Quickly create three-dimensional flow and transport models
  • Significantly reduce model development cost
  • Develop very large, high-resolution regional models
  • More accurately and efficiently compute hydraulic head and solute concentration solutions (grid refinement is automatically added in regions of high head and/or concentration gradients)
  • Quickly change the grid resolution by simply varying the number of AMR levels
  • Accurately simulate thin and highly-stratified plumes (the higher-order Eulerian-Lagrangian transport solution significantly reduces numerical dispersion)
  • Take advantage of multiple-core processors
  • Use much larger time steps when simulating advection-dominated transport
  • Reduce computational effort (the simulation time step is automatically adjusted based on the velocity field and cell sizes
  • Visually monitor simulation progress during model runs
