WASY FEFLOW 5.301

WASY FEFLOW is a professional finite-element modeling system for simulating groundwater flow as well as mass and heat transport in porous and fractured media. Developed by WASY, it supports both 2D and 3D analyses and is built for complex hydrogeologic settings, from regional aquifers to detailed site-scale studies. Its interactive environment helps users build conceptual models, generate meshes, assign properties and boundary conditions, run simulations, and visualize results with clarity.

Key capabilities:

• Groundwater flow under saturated and variably saturated conditions
• Transport of solutes and heat, including advection, dispersion, diffusion, sorption, and decay
• Variable-density flow driven by salinity and temperature gradients (e.g., saltwater intrusion, geothermal applications)
• Flexible meshing with layered and unstructured elements to capture complex geology, anisotropy, and heterogeneity
• Rich set of boundary conditions for recharge, rivers, drains, wells, seepage faces, and more
• Pre- and post-processing tools for data import, quality control, time-series management, and visualization (maps, sections, pathlines, and budgets)
• Model calibration and uncertainty analysis, including parameter estimation workflows (e.g., FePEST)
• Scripting and extensibility options for automation and custom workflows, with support for data exchange and GIS integration

Typical applications:

• Groundwater resource assessment and wellfield design
• Contaminant plume forecasting and remediation planning
• Mine dewatering, tunneling, and construction dewatering analysis
• Saltwater intrusion studies in coastal aquifers
• Geothermal and heat transport evaluations
• Evaluation of interactions between groundwater and surface-water features

WASY FEFLOW combines a robust numerical core with a practical user interface, enabling scientists, engineers, and consultants to analyze complex subsurface systems and make confident, defensible decisions.
