      • Control all groundwater wells (flow, mass and heat) from a central locationUsing FEFLOW 8.0’s new Well Manager, it’s easier than ever to create, edit and delete Well BC, Multilayer Wells and BHEs, the most important boundary condition in a groundwater model. With just a few clicks, users can import hundreds of wells to gather feedback on problem classes and to identify whether a groundwater well already exists.
      • Streamline well management and optimisation with the enhanced Well Manager EditorThe updated Well Manager Editor simplifies well management by allowing users to group diverse well types, whether they are water or geothermal wells, for more streamlined operations. The Well Manager Editor is evolving into an ‘orchestrator,’ offering users the convenience of testing and applying rules to well groups effortlessly. This transformation in functionality greatly boosts efficiency by enabling users to efficiently handle wells within these groups and apply rules to them, resulting in more efficient and effective well management processes. Watch the video
      • Optimise well management with three versatile new Well Manager rulesFirst, streamline well management with the ‘Inactive Wells’ rule, which enables hassle-free deactivation while retaining data integrity. This ensures you can efficiently manage inactive wells without compromising the integrity of your data. Second, enhance efficiency with the ‘Shared Properties’ rule, which simplifies property changes across multiple wells to ensure consistency. This rule streamlines the process of making property changes, reducing errors and maintaining uniformity across your well portfolio. Lastly, achieve pump rate distribution more efficiently using the ‘Distributed Rate’ rule, which allocates rates equally among wells for optimal performance. This helps maximise the productivity and effectiveness of your well operations by ensuring an even distribution of pump rates. Watch the video
