FEFLOW® (Finite Element Flow) is the most advancedf groundwater modelling package available. This state of-the-art program provides a fylly 3-Dgraphical modelling environment for performing complex groundwater flow, contaminant transport, and heat transport modelling.
Advanced Capabilities
FEFLOW has been specifically designed to meet the advanced technology requirements of expert modeling professionals involved in complex groundwater modeling projects. The state-of-the art graphical features and powerful analysis capabilities allow FEFLOW to excel where most popular groundwater models will fail misearably.
• Fully-transient, semi-transient and steady-state groundwater flow and contaminant transport processes
• Time-varying material properties and constrained boundary conditions
• Saturated and/or unsaturated flow
• Confined and unconfined aquifers, multiple free surfaces for perched water tables
• Chemical mass transport with nonlinear sorption, decay, convection, and dispersion
• Fluid and Solid heat transport with storage, convection, thermo-dispersion, and heat-transfer
• Density –dependent flow (e.g saltwater intrusion, buoyant heat transport)
