GeoStudio FLOW and 3D FLOW

GeoStudio FLOW + 3D FLOW

GeoStudio FLOW is a multi-physics 2D finite element software package for modelling environmental protection, groundwater flow, climate, and ground freezing problems. The powerful features available in SEEP/W, TEMP/W, CTRAN/W, and AIR/W are included, giving you the ability to simulate simple saturated only, steady-state problems through to complex scenarios that require coupling of water, heat, gas and/or solute physics.

GeoStudio 3D FLOW extends this modelling package to simulate into the third dimension ​with SEEP3D, TEMP3D, CTRAN3D, and AIR3D analysis options. BUILD3D, the feature-based ​geometry creation tool in GeoStudio, is also included, allowing you to construct complex 3D models.

Combine GeoStudio FLOW with 3D FLOW to meet all your multi-dimensional modelling needs​.

Key Features

Seamless Integration

Integration between products gives you the power to simulate complex, fully coupled scenarios. For example, TEMP/W can be fully-integrated with both SEEP/W and AIR/W to consider forced convection via groundwater and/or air flow. This integration is included in both the 2D and 3D FLOW packages, allowing you to simulate multi-physics in all dimensions.


Material Properties

Both GeoStudio FLOW and 3D FLOW use the same familiar material properties from SEEP/W, TEMP/W, CTRAN/W and AIR/W. This allows you to consider both saturated and unsaturated formulations, including dual phase air and gas transfer.

Boundary Conditions

A range of boundary condition options are available in both the GeoStudio FLOW and GeoStudio 3D FLOW packages. Field data or user-specified functional relationships can be used to define hydrographs, reservoir fluctuations, thermosyphon, convective heat transfer, n-Factor, and many more boundary conditions.

Land-Climate Interactions

Analyze problems that involve a coupling between climatic conditions and both the hydraulic and thermal response within the ground in SEEP/W and TEMP/W using the land-climate interaction and surface energy balance boundary conditions. Consider air or gas entrapment in the soil by adding AIR/W and CTRAN/W.

GeoStudio FLOW and GeoStudio 3D FLOW can analyse almost any environmental, groundwater, or geothermal problem.

Environmental Protection

Solve problems related to mine site and landfill closure, contaminant transport and remediation, and the design and operation of mines that minimize the impact on the environment. GeoStudio FLOW and GeoStudio 3D FLOW allow you to simulate differing levels of complexity, including steady-state and transient processes or the coupling of heat, gas, and water fluxes with contaminant transport analyses.


Groundwater is a significant source of fresh water in the world, making the management of those resources important. GeoStudio FLOW and GeoStudio 3D FLOW can be used to simulate the hydrogeological behaviour of a groundwater system under both long-term, steady-state conditions and dynamic, transient conditions.

Ground Freezing and Climate Change

The thermal response of the ground can be a major concern for many engineering and earth science problems, including degradation of permafrost due to construction or climate change, artificial ground freezing during construction activities, and the effect of convective heat transfer on earth embankments or soil cover performance. GeoStudio FLOW and GeoStudio 3D FLOW can consider heat transfer with phase change, due to conduction and convection.

Vadose Zone Hydrology

Understanding flow in the vadose zone can be challenging due to complex processes and interactions near the ground surface from climate and vegetation. GeoStudio’s multi-physics solver can seamlessly couple mass and heat transport processes required for projects including the design of soil covers for mine or municipal wastes.

Caesium 137 Transport

Caesium-137 (Cs-137) is an anthropogenic radioactive isotope formed as a product of nuclear fission. The objective of this example is to analyze Cs-137 transport into an unconfined aquifer using CTRAN/W. The effect of adsorption and decay on solute concentrations and mass discharge is highlighted.

Dewatering - Deep well systems

This example illustrates how to model deep well systems in three-dimensional environments, and verifies the water-flow formulation against a well-known benchmark. In so doing, the example discusses a specific deep well system, and provides insight into an approach for modeling pumping wells.
