Did you know you can run models simultaneously in ExtendSim 10? Yes, you certainly can. That feature has been in ExtendSim since v10 was released, but I often run into ExtendSim users who are not aware of the feature. It is one that I make use of all the time.

In computer science and engineering a race condition is "an undesirable situation that occurs when a device or system attempts to perform two or more operations at the same time, but because of the nature of the device or system, the operations must be done in the proper sequence to be done correctly". In discrete event simulation programs such as ExtendSim, a race condition is when multiple events happen at the same simulated time and the order of these events has an impact on the operation of the model. Because discrete event simulators process events at discrete times, race conditions are fairly common.

It is an excellent idea to make a backup of your model from time to time. This could be useful if you want to go back and open a previous model version. In order to do that, you should periodically make a complete backup of your model and any additional files it might need. You might not be able to run an old model if you don’t. The complete archived model should include the same elements you would need to include if you sent the model to someone else to run.
