On the basis of an example data set, we will build a three-dimensional flow and transport model applying the most important program functions (preprocessing, simulation, result evaluation).
Main Topics:
- Introduction to flow and mass-transport modeling
- Physical and mathematical basics of modeling with FEFLOW
- Introduction to FEFLOW's Graphical User Interface
- Setting up a 2D and 3D flow model by using (GIS-/CAD-) data interfaces
- Extending the model to include contaminant transport

FEFLOW 6 Standard User Interface
September 6, 2012, 9 am to 5 pm
This course provides a quick introduction to the FEFLOW 6 Standard interface for 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 with the Classic interface no longer being available. The focus of the workshop is on GUI handling, applications or modeling questions will not be discussed.
Requirements: Experience with FEFLOW in Classic mode
Training fee:
200 € with FEFLOW SMA
250 € without FEFLOW SMA
Geothermal Modeling
September 6, 2012, 9 am to 5 pm
This training session will provide an introduction to the numerical simulation of geothermal facilities using FEFLOW. Both deep and shallow geothermics will be studied by setting up specific modeling applications. Of particular importance for deep geothermics is the coupling of flow and transport processes via temperature and pressure dependencies of fundamental process parameters such as fluid density, fluid viscosity and thermal conductivity. Shallow geothermics will also be discussed in detail, for instance the numerical modeling of single and arrays of borehole-heat exchangers. These topics and their implementation and handling in FEFLOW will be discussed.
Requirements: Experience in flow modeling with FEFLOW

200 € with FEFLOW SMA
250 € without FEFLOW SMA
Unsaturated-Flow Modeling
September 6, 2012, 9 am to 5 pm
In this workshop, the modeling of flow and transport processes in unsaturated or variably saturated media is discussed. After an introduction of the theoretical background (Richards' equation, parametric relationships, hysteresis effects) practical example models for different applications are set up in FEFLOW.
Requirements: Experience in using FEFLOW for saturated flow models

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.leapfrog3d.com). All participants will receive limited-duration licenses for Leapfrog Hydro to hone their skills after the course.
Training fee:
400 € with FEFLOW SMA
500 € without FEFLOW SMA
