<p>Amir,</p>
<p> Almost all of TRNSYS's outputs are averages over a timestep.
Without modifying the Type39 code I cannot think of a way to get
the end of timestep volume. Would it be feasible to shorten the
time step? That way presumably the difference between the average
value and the end value would be reduced.</p>
<p>kind regards,</p>

<div>I noticed today while i was trying to match my manual
calculation with that of Type 39 (Variable Volume Tank) for
the tank volume that they do not match.</div>
<div><br>
</div>
<div>The reason for such discrepancy, i noticed, is because the
volume calculated by Type 39 is the average at a certain time
step rather than at the final step.</div>
<div><br>
</div>
<div>My question is, is there a way Type 39 can output the
volume at the final step instead of average value?</div>
<div><br>
</div>
<div>The issue is that in my model there are few parameters that
are manually calculated and they are a function of the tank
volume</div>
