Dear all, <div><br></div><div>I have problem again with simulation time step,</div><div><br></div><div>I use Type 9 data reader, with 5 minutes time step data,</div><div>1. How to write the simulation start time in (type 9) if I simulate it together with weather data in June (in type 109)?</div>
<div>2. I did a test with my data file, I connect type 9 with online plotter, I put data in type 9 like the note bellow,</div><div> and I set simulation start time 0 stop time is 120, when I set simulation time step to 5 minutes the simulation error, </div>
<div> but when simulation time step to 2.5 minutes, the simulation run, </div><div> Do I need to set simulation time step in control card below 5 minutes if the data is in 5 minutes interval?</div><div>3. I run my complete simulation, with type 9 and type 109, I set simulation time step to 2.5 minutes, i run simulation for a month,</div>
<div> but the simulation run only for several hour and then stopped, I got some warning:</div><div><br></div><div>simulation log:</div><div><div>Radiation while sun is down found 1 times <font class="Apple-style-span" color="#000099">(What is this?)</font></div>

type 109 with 5 minutes time step<br>
</font><br>
</div><div><div></div><div>
<div></div>
<p>
Dear all,
</p><div><br>
</div>
<div>I have 5 minutes time step weather data,
</div>
<div>How to conduct simulation with 5 minutes time step using type
109,
</div>
<div>do I need to change something in the .109 data file?
</div>
<div>I've try to just change the data in .109 file from 1 hour time step with my
5 minutes time step data
</div>
<div>but when I run simulation with 5 minutes time step the results become
weird,
</div>
<div>Thank you very much
</div>
<div><br>
</div>
<div>Regards,
