Summary

This five-day, hands-on course provides you with comprehensive training in groundwater modelling using FEFLOW. It consists of an introductory and an advanced part. The introductory part provides a comprehensive overview over the most important parts of groundwater modelling with FEFLOW, from mesh generation to transient and variably saturated flow simulations, while the advanced part focuses on more complex modelling topics such as geothermal energy applications and modelling of the transport of reactive solutes. There will be ample opportunity to discuss groundwater topics with some of DHI’s most experienced groundwater modelers, and plenty of time to ask questions.

FEFLOW is widely recognised as a comprehensive software package for subsurface flow and transport simulation. FEFLOW’s unique meshing capabilities (structured and unstructured) allows for the highest degree of flexibility to account in detail for the simplest all the way to the most complex geometrical configurations. The software is used by leading research institutes, universities, consulting firms and government organisations all over the world. FEFLOW’s scope of application ranges from simple local-scale to complex large-scale modelling. Applications include water resources management, mine dewatering, saltwater intrusion, and geothermal energy.

 

Target audience

PhD school members, academics and professionals from a wide range of backgrounds will benefit from this course, whether new to groundwater modelling or already experienced modelers.
