<p>Michel,</p>
<p> It does sound as though there is an issue with one of the
printers or integrators resetting. Your Type55 parameters look
okay to me. Usually Type55 feeds into a Type25 printer. Make sure
that the print time (print interval) is set to 8769 as well (so
long as you want only one value printed at the end of the
simulation.)<br>
</p>
<p> Another thought is that unless you have to run your simulation
for more then a year (ie if the time has to go beyond 8769) then
you could set all of the integrator reset times and print times to
the variable name "STOP." STOP is a built-in variable that is the
hour on which the simulation should end.</p>
<p>kind regards,</p>
<p> David</p>

<div>Dear all, <br>
</div>
<div><br>
</div>
<div>I am running my simulation for one year period. Starting
simulation time is 9 hr and stopping simulation time is 8769
hr. However, regardless of the step time all values are
reset to 0 around timestep of 8765 hr and above. Can someone
please explain to me why this is happening? Because now I am
not sure if my end values used within TRNOPT are correct for
the optimization. Could have something to do with using Type
24 and Type 55?</div>
<div><b><br>
</b></div>
<div><b>For Type 55 I am using the following parameters:</b></div>
<div><b><br>
</b></div>
<div><b>Parameter 1: Integrate or sum input-1 -1 <br>
</b></div>
<div><b> Parameter 2: Relative starting hour for input-1

</b></div>
<div><b> Parameter 3: Duration for input-1 8769 <br>
</b></div>
<div><b>Parameter 4: Cycle repeat time for input-1 8769
<br>
</b></div>
<div><b>Parameter 5: Reset time for input-1 8769 <br>
</b></div>
<div><b>Parameter 6: Absolute starting hour for input-1
0 <br>
</b></div>
<div><b>Parameter 7: Absolute stopping hour for input -1
8769 </b><br>
</div>

<div>Any kind of help is more than appreciated!</div>
<div>Thanks in advance!</div>
