JaamSim 2026-04 released

[Harry King]

Changes in release 2026-04:

• 'ServiceDuration', 'ServicePerformed', and 'FractionCompleted' outputs for EntityProcessor. These outputs are provided to make the EntityProcessor object consistent with the Server object. Note, however, that for an EntityProcessor these outputs return an array of values (one for each entity being processed) instead of a single value.
• Option to delete an unused DisplayModel. Two objects are created when an image file or 3d file is imported: 1) a DisplayModel that holds the graphics data, and 2) a DisplayEntity that appears in the model. The DisplayModel is an ImageModel in the case image file and a ColladaModel in the case of a 3d file. If the imported DisplayEntity is deleted, it is easy to forget to delete the DisplayModel that references the file. To avoid a model becoming cluttered with unused DisplayModels, the user is now prompted to delete a DisplayModel that becomes unused when the only DisplayEntity that references it is deleted.
• 'ScriptedViewDirection' input for View. This input replaces the 'ScriptedViewCenter' input to be consistent with the 'ViewDirection' input that was introduced in release 2026-03.
• 'UserList' output for DisplayModel. This output lists all the objects that use this DisplayModel for their graphical display.
• Bug fix for model execution on multiple threads. The ability to run models on multiple threads has been restored. This feature was broken accidentally in release 2026-01.
• Bug fix for file streams. Connections to input and output files are closed correctly when an error occurs.
