DHI has released MIKE 2025 Update 1, the latest version of its MIKE Powered by DHI software suite for water modelling. This update delivers new features and enhancements across key products, aimed at supporting engineers and water professionals in their work. This update is available at no additional cost for clients with an active Service Maintenance Agreement (SMA) or subscription.

What's new in MIKE 2025 Update 1

• MIKE+ introduces an updated discharge calculation tool that streamlines the estimation of flows through sections from 1D and 2D results directly within MIKE+. Rivers and Collection System models have a new workflow to associate simulations with various rainfall events, saving time and increasing flexibility. Additionally, a new Water Hammer engine brings faster simulations, Linux support and check valve modelling. 
• FEFLOW 10 empowers users to present models with enhanced online 3D terrain visualisation including a new Online Maps toolbar that provides full control over visualisation settings and map types, and introduces new features to search for locations, coordinates and more. Additionally, a new ‘Create surface from Supermesh elements’ tool enables the generation of 3D surfaces from point data—no external geological software needed. Plus, the fully integrated smh3d format supports all legacy 3D functions and offers improved mesh repair capabilities to better handle complex geological intersections.
• WEST now comes with a built-in compiler and full 64-bit support, boosting compilation and simulation speed. The full transition to the Modelica language brings greater flexibility for advanced modelling. In addition, automatic mass flow tracking makes it easier to calculate and verify component mass balances across the plant, while improved tools for micropollutant and N₂O modelling enhance support for plant upgrades and optimisation. Lastly, the WEST interface is now also available in French.
• MIKE WaterNet Advisor now includes a step-by-step user guide that streamlines onboarding and aligns with digital twin workflows. Smart features like disk space alerts, improved contact time calculations and model-based valve support in shutdown planning make it easier to maintain water quality and network performance.
• MIKE OPERATIONS features a new MIKE Modelling Workbench that provides a unified environment to prepare, process and visualise data from folders, GIS or the cloud. MIKE SHE users can now build real-time forecasting tools in just hours, thanks to enhanced input raster processing, adaptors and hotstart support. Updated time series tools streamline data import and model setup, while improved Python integration allows users to leverage their favourite libraries.
