Conditionals

Events generally occur when conditionals in the model change. For example, a step is modeled as

y = if time < 1 then 0 else 1;

At time = 1 an event occurs. This snippet is written in Modelica, which MapleSim uses as the model language. MapleSim parses the Modelica language, generates Maple code with events that can be handled by dsolve (it's significantly more complicated than that, but that's the basic idea).

On a related note, dsolve's event handling was introduced in Maple 12, just in time for MapleSim 1. Of course, it can also be used without MapleSim. The ?dsolve,numeric,Events page has all the details.
