Running Multiple Digital Twins at the Same Time

The DTaaS platform can execute several digital twins at once. This saves time with long-running digital twins or when they run on different resources.

Running Digital Twins

To run a digital twin, open the Execute tab of the Digital Twins Page. Click Automation in the menu on the left, then click the Digital Twins Page card. The page opens in the same browser tab.

The Execute tab shows a card for each digital twin, with its name, a short description and the Start and History buttons. Start sends a job to the backend, which runs the simulation defined by the digital twin's lifecycle files. You can inspect and change these files with the Reconfigure button on the Manage tab.

Running Multiple Twins

Pressing Start several times queues several simulations. You can also queue different digital twins.

The deployment service (for example, GitLab) balances the load across the available runners, so it can be configured once and then left to run.

The Execution Log

History opens a list of all current and past runs, showing the time of execution and the status (Running, Completed, Failed, Canceled or Timed out). To review the results of a run, click an entry (or the arrow on the right of the entry) to expand it. The log of each job in the pipeline is then shown.

To delete an entry, click the trash icon and confirm the deletion in the dialog. The Clear All button deletes all entries of a digital twin.

Click the stop icon of a running entry to stop that execution:

Changing Runners

The runners that pick up jobs can be changed in the settings. See these and other settings.
