Termination Time

Termination Time

Apr-23-14 07:43:34

Hi,
I created a simple model in which i have a cylindrical tank open at one end. (I know the tank volume) The flow rate is the parameter. My model is such that it terminates when tank volume = flow rate * time. (I used the terminate() condition).  Is there any way to store this termination time in a variable?

Perhaps the following works for you:

Code:

model M

  discrete Real r(start=0, fixed=true);

equation

  when time>0.5 then

    terminate("end");

  end when;

  when terminal() then

    r = time;

  end when;

end M;

I get the expected output:

Code:

$ ./M -output=r

[/home/martin/tmp/a.mo:5:5-5:21:writable]

stdout            | info    | Simulation call terminate() at time 0.500000

|                 | |       | Message : end

time=0.50000000015000567455,r=0.50000000015000567455

Thanks. Works like a charm.
