Description
Consider the model
model Test Real x(start=1); equation der(x) = -2 * x; when time > 0.5 then reinit(x,-1); end when; end Test;
At the time of event (time = 0.5) there are stored two data points:
{{{t_1 = 0.499999023437500, x_1 = 0.36
t_2 = 0.500000000000000, x_2 = 1.00}}}
Times t_1 and t_2 should be identical (t_1 == t_2), but are not.
This is fine for plotting, but it is very impractical, since from the results it is impossible to determine if we are dealing with discontinuity of with just very short continuous time interval! As a consequence, some postprocessing algorithms might fail.
Maybe this should be even reported as a bug?!
