How can I customize the units for display of results?
MIKE+ 2026 Update 1 introduces customizable result display units through the User Preferences → Result units tab settings (accessed from ‘File’ menu) - see Figure 1. Users can define display units for individual result item types while maintaining physical and numerical consistency with the selected preferred unit system.

The customization may be applied on two levels: on the current project database and for result viewing mode (when only result files are loaded), these changes are designed to take effect on the local computer, consequently the customization will apply to all projects opened on that computer.
In “Customized result units” table, users can add as many entries as needed to modify the displayed units. When a new entry is created, the combo-box field allows the user to select the result item type from a predetermined list of physical properties, as shown in Figure 2.

On the right-hand column the user can select the units preferred through a combo-box field, from a dynamic list.
As presented in Figure 3, the units displayed are consistent with the result item chosen. The user is not allowed to overwrite the existing options to prevent fundamental inconsistencies.

The unit customization can be saved as a "Result Units File' (see Figure 4) as a configuration scripting file (*.json file), allowing shareability and traceability of the changes.

This file can be opened and edited in any text editor; allowing the user to modify the configuration directly. However; this approach requires familiarity with the internal code identifiers implemented in MIKE+. The file contents do not include result item description or units; instead, they reference the corresponding internal IDs.
As an example, the figure below shows five result items whose units have been customized. If these customizations are exported to a configuration file and the file is opened in a text editor, the contents will be presented as shown in Figure 5. It can be seen that the configuration consists of a series of internal code values which are not easily interpreted without prior knowledge of the associated MIKE+ identifier. As a result, understanding or modifying the configuration directly in the text file can be challenging for users who are unfamiliar with these internal codes.

The contents on the script can be interpreted as shown in Table 1. Understanding this mapping is particularly useful when users need to share configurations or perform bulk modifications to multiple result items.

Conclusion
The result unit customization feature in MIKE+ 2026 Update 1 provides a flexible and user-friendly way to modify result units' presentation while maintaining consistency with the selected unit system. By supporting reusable JSON-based configuration files, the feature enhances portability, standardization, and traceability, enabling users to easily share, apply and maintain consistent result-viewing preferences across projects, teams and organizations.
