<p>Nina,</p>
<p>I'm not sure what you are asking. In most district loop projects we have done, the piping network make a complete closed path. If it's a single pipe system the loads divert from and return to the main loop. In a two-pipe system, the flows leave from the supply pipe and return to the return pipe which runs in parallel with the supply pipe. </p>

<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: #000000;"> </div>
<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: #000000;">I'm trying to create a district heating type of loop. I'm not sure how to reconcile the values of my loop.</div>
<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: #000000;">Does anyone know how can I use the values of the previous iteration in the next one? If this is possible, how do I set initial values?</div>
<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: #000000;"> </div>
<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: #000000;">Many thanks,</div>
