Generate and Destroy Entities and Messages
R2026bDiscrete-event simulations typically involve discrete items of interest, called entities in SimEvents® software. You determine what an entity signifies, based on what you are modeling. Generate entities, and inspect their structures. Use the Entity Generator block to specify custom entity intergeneration times. Use the Entity Terminator block to terminate entities. For more information, see Entities in a SimEvents Model.
Blocks
 | Entity Generator | Generate entities |
 | Entity Terminator | Terminate entities |
 | Entity Replicator | Replicate entities |
 | Hit Crossing | Detect crossing point |
 | Send | Create and send message |
 | Receive | Receive messages |
