Dear all,<br><br>I successfully simulate a micro-CHP system coupled with thermal storage (Type 534) in TRNSYS.<br><br>TRNOpt works perfectly well on a number of other simulations.<br><br>However, when I couple TRNOpt with this simulation, GenOpt only runs the Initialization simulation, and then "waits" for about one to two hours and stops, prompting the following error message:<br>
<br><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote">Initialize.<br>java.lang.OutOfMemoryError: <br>Java heap space<br><br>GenOpt terminated with error.<br>
See logfile for further information.<br></blockquote><br>The logfile doesn't provide any further information.<br><br>I noticed that removing the heat storage tank solves the problem, as well as reducing the number of tank nodes (parameter 2) to 2. But those actions reduce drastically the precision of the simulation.<br>
<br>Has anyone already met this problem with the optimisation process?<br>Any idea where it may come from?<br><br>Any help would be appreciated.<br><br>Thanks,<br>Benoît<br><div>
