Description

Running the Printing model below:

model pp
 parameter Boolean use_eps_Re = false;
initial equation
 if not use_eps_Re then
    Modelica.Utilities.Streams.print("This message is printed a lot of times\n");
 end if;
end pp;

model Printing
  pp p1;
end Printing;

gets you this output:

true

Same happens for assert(..., "Message", warning); instead of print.
But only 7 times it seems :)
See the output of some of the AVM models.

comment:3 by Adrian Pop, 13 years ago

Of course, as Martin points to me via Skype it seems to depend on how many instances of Modelica.Fluid.System are used in the Model, so our mileage might vary.

Modelling error:

With the prefix keyword impure it is stated that a Modelica function is impure and it is only allowed to call such a function from within:

another function marked with the prefixes impure or pure
a when-equation, or
a when-statement.

print is impure (although we do not support this feature yet, etc).

If you want to make another ticket to avoid evaluating the initial equations many times (for performance reasons), feel free to do so. The function should be called at each step to ensure it triggered no assertions.

Note: See TracTickets for help on using tickets.
