Unsaturated-flow modelling: From theory to model implementation
Presenters: Dr. Milan Pelletier and Dr. Carlos Andres Rivera Villarreyes
The Richards’ equation represents the water flow movement through the unsaturated zone (vadose zone). The modelling of unsaturated flow was introduced in FEFLOW already since its version 4.x and dated back to 1997. Since then, FEFLOW modellers have been using the Richards’ problem class to solve a wide range of applications from seepage analysis, mine dewatering, fate of contaminants through the vadose zone, among others. In this half-day workshop, Dr. Pelletier and Dr. Rivera Villarreyes will reveal in a “digestible” manner the details behind the implementation, covering basic physical and numerical backgrounds. In addition, this workshop will have use for presenting latest FEFLOW’s developments in respect to unsaturated-flow modelling.

Getting the most out of the FEFLOW – Python interface
Presenters: Dr. Francesca De Gaspari and Sophie Gruschka
The FEFLOW Programming Interface has become part of the daily workflows of groundwater modellers. In this half-day workshop, Dr. De Gaspari and Ms. Gruschka will give you a several tips and tricks for getting the most out of the FEFLOW-Python interface. The workshop will be used as well as platform to present the latest developments on the FEFLOW-Python interface.

FEFLOW 3D unstructured meshes: Best practices
Presenters: Dr. Carlos Andres Rivera Villarreyes and Sophie Gruschka
We know geology can get complex many times. FEFLOW’s unique meshing capabilities (structured and unstructured) allow you for the highest degree of flexibility to account such as details. In this half-day workshop, Dr. Rivera Villarreyes and Ms. Gruschka will give an overview of the different alternatives for processing such as complex systems and subsequently, the corresponding 3D mesh generation. The workflow is intended to equip you with the “best practice” workflows to handle the implementation of several complex geological and geotechnical structures in FEFLOW 3D meshes.

Uncertainty quantification using FEFLOW and PEST++
Presenter: Dr. Francesca De Gaspari
In this half-day workshop, we will provide you the uncertainty quantification for subsurface models. Using the FePEST, graphical interface of PEST and PEST++ for FEFLOW models, Dr. De Gaspari will demonstrate the workflow for model calibration and uncertainty quantification. Through a hands-on exercise, the implementation and use of the Iterative Ensemble Smoother will be demonstrated for calibrating a FEFLOW model and estimating the uncertainty of the model predictions.

Topics include:
- Phreatic aquifers, when do we use pseudo-saturation and Richards equation?
- What do you consider a good mesh for flow and mass transport simulations?
- Overcoming numerical stability problems together: An overview of the different options, from mesh optimization to upwinding
- Reactive and multi-species transport: FEFLOW, PHREQC, or both together?
- Putting some density to the problem: In a nutshell, what are the necessary settings and concepts for density and viscosity-driven flow simulations?
- Matrix and fractures: What can we do for flow and mass transport modeling?
- Yes, we go unstructured! What can you get from it?
- Open discussion
