MIKE+| Running multiple detached simulations

DESCRIPTION

For projects defined as 'Rivers, collection system and overland flows', the simulation engine can now be executed as a standalone independent process from the activity occurring on the graphical user interface session. This option enables decoupling model execution from the MIKE+ workspace. 

This promotes a more efficient use of computational resources by allowing parallel workflows to run together with simulations.

WORKFLOW

This functionality is enabled through the “Run detached” button within the "Simulation setup" editor introduced in version 2026. By initiating simulations in detached mode, the computational process is executed independently of the MIKE+ graphical user interface, permitting multiple simulations to be run concurrently from the same MIKE+ project. 

Furthermore, this approach allows to close the MIKE+ application while simulations remain in progress, effectively releasing the associated license seat for immediate reuse by another user or on a different machine. It should be noted that, when a simulation is initiated using the standard “RUN” command, the user is still presented with the option to continue execution in a standalone window upon closing MIKE+. This behavior is illustrated in Figure 1.

This functionality is useful in situations where greater flexibility and efficiency in simulation execution is required. This allows users to:

1. Release a user interface license seat while simulations are running in the background, allowing a more efficient use of available licenses. 

2. Executive multiple simulations from the same MIKE+ project in parallel (for example, different scenarios within the project). Overcoming the limitation pose by the "RUN" button that only sequential one-at-a-time executions are supported. 

CONCLUSION

This feature results in a functionality that improves license utilization and reduces significantly turnaround time by enabling concurrent, non-interactive model execution.
