Hi,
I tried out the sample function and it do not sample as it should. Am I doing something wrong or is it a bug? Her is the code:
-----------------------------------------
model Sampling
discrete Real r;
equation
when sample(0,0.5) then
r = pre(r)+1.0;
end when;
end Sampling;
-----------------------------------------

When I run this it does not always trigger the sample event. It is solved with:

simulate(Sampling, startTime=0, stopTime=30, numberOfIntervals=500, tolerance=1e-6, method="dassl", outputFormat="mat");

I run version 1-7.0 r8273


Great work with Open Modelica, thanks a lot!
