No time events in OpenModelica?

[Andreas Nicolai <andreas.nicolai@…>]

Hi there,

I've just tried an example from Michael Tiller's ebook:
​http://book.xogeny.com/behavior/discrete/cooling/#cooling-revisited

with the following minimalistics example:

model TimeEventModellTest
  Real T_inf;
equation
  if time<=0.5 then
    T_inf = 298.15 "Constant temperature when time<=0.5";
  else
    T_inf = 298.15-20*(time-0.5) "Otherwise, decreasing";
  end if;
end TimeEventModellTest;

Solver statistics shows:
1 state events
0 time events

Clearly, this code should trigger a time event, since the condition only depends on time. Am I missing something here or is maybe the statistics output broken?

This is an old issue that still needs to be fixed, sse #2152. AFAIK, only in the case of sample() operators does the current runtime generate time events.
