On the basis of an example data set, we will build up a three-dimensional flow and transport model applying the most important program functions (pre-processing, simulation, result evaluation).

Main Topics:

  • Introduction to flow and mass transport simulation
  • Physical and mathematical basics of the modeling using FEFLOW
  • Introduction to the FEFLOW Graphical User Interface
  • Setting up a 2D and 3D flow model by using (GIS-/CAD-) data interfaces 
  • Extending the model to include contaminant transport
  • Pre and post-processing of the model data

 Training fee:
                      700 € with FEFLOW SMA
                      900 € without FEFLOW SMA

FEFLOW 6 Standard user interface


September 6, 2012, 9 am to 5 pm

This course provides a quick introduction into the FEFLOW 6 Standard interface to experienced users of the Classic interface. The main goal is to enable users who had stayed away from the Standard interface in version 6.0 to continue their work seamlessly in 6.1 where the Classic interface is no longer available. The focus of the workshop is on GUI handling, no applicaitons or modeling questions are discussed.

Requirements: Experience with FEFLOW in Classic mode

Training fee:
                      150 € with FEFLOW SMA
                      200 € without FEFLOW SMA

Geothermal Modelling


September 6, 2012, 9 am to 5 pm

This training session will give an introduction into the numerical simulation of geothermal facilities using FEFLOW. Both deep and shallow geothermics will be studied by setting up specific modelling applications. Of particular importance for deep geothermics is the coupling of flow and transport processes via temperature and pressure dependence of fundamental process parameters such as fluid density and viscosity, and thermal conductivity. Furthermore the modelling of fracture flow is often an issue at stake. An additional focus points will be shallow geothermics, for instance the numerical modelling of single and arrays of borehole heat exchangers. These issues and their treatment in FEFLOW will be explained.

Requirements: Experience in flow modelling with FEFLOW

New Approaches to Conceptual Modelling Development


Instructors: Thomas D. Krom & ARANZgeo staff

Time: 8:30 a.m. - 4:30 p.m. over 2 days (September 6 - 7, 2012)

Developing a reasonable geological model is a key activity in many hydrogeological studies. This course will provide you with tools and skills for getting the most out of your data while constructing a conceptual hydrogeological model for your site. Additionally, the course will focus on how applying implicit modelling concepts allows you to do this faster by moving the focus onto building the conceptual model and using software tools to carry out the drudgery (like finding contacts in wells and data checking).

The course includes examples for water resources and contamination problems. The course is a series of hands-on modelling exercises in geological model construction as well as how to transfer the geological model to FEFLOW models. Exercises also include using data verification tools for easy error-checking, 3D interpolation of data on screens. Volume calculations for contaminate plumes is also covered. There is a case study on how to use geophysical data directly in the model building process.

The course uses the Leapfrog Hydro software (www.leapfroghydro.com). All participants will receive limited-duration licenses for Leapfrog Hydro to hone their skills after the course.

Training fee:
                      300 € with FEFLOW SMA
                      400 € without FEFLOW SMA
