<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am running my simulation with a type 512 heat exchanger and I get the following warning message (no convergence errors, just warnings) at the end of my simulation (time step: 0.1 hour):<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">*** Warning at time : 39384.000000<o:p></o:p></p>
<p class="MsoNormal"> Generated by Unit : 45<o:p></o:p></p>
<p class="MsoNormal"> Generated by Type : 512<o:p></o:p></p>
<p class="MsoNormal"> Message : Heat exchanger mass balance failed during 112810 time steps. Please check the connections.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I do not understand what could be the reason for this. I have gone through my connections and they all seem fine (I do not get this problem with heat exchanger type 91).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks for your help,<o:p></o:p></p>
