<div>Sandeep,<br>
TRNSYS has three levels of notifications: "notices" are for informational purposes only, "warnings" are a potential issue and should be investigated further to determine whether they are serious or not, and "fatals" are errors that will stop a simulation
immediately. If you are getting a non convergence warning for 10 timesteps in an annual simulation then there is nothing to worry about. If you are getting non convergence warnings for 10 timesteps out of a 10 timestep simulation then it is an issue that needs
to be addressed.<br>
kind regards,<br>

<p class="MsoNormal" style="margin: 0in 0in 10pt;">Hello TRNSYS users, </p>
<p class="MsoNormal" style="margin: 0in 0in 10pt;">I have few general questions regarding the warning and messages in TRNSYS. My model giving results but at the same time its giving; warning and messages. I have mainly three questions
</p>
<p class="MsoListParagraphCxSpFirst" style="margin: 0in 0in 0pt 0.5in; text-indent: -0.25in;">
<span><span>a.<span style="font: 7pt/normal "Times New Roman"; font-size-adjust: none; font-stretch: normal;">
</span></span></span><span> </span>Is it necessary to fix all of the warning and messages?
</p>
<p class="MsoListParagraphCxSpMiddle" style="margin: 0in 0in 0pt 0.5in; text-indent: -0.25in;">
<span><span>b.<span style="font: 7pt/normal "Times New Roman"; font-size-adjust: none; font-stretch: normal;">
</span></span></span>Can we assume that our results are realistic even we have warning? (if there is no error)</p>
<p class="MsoListParagraphCxSpLast" style="margin: 0in 0in 10pt 0.5in;"> </p>
<p class="MsoNormal" style="margin: 0in 0in 10pt;">For instance, In my model there are few notices and warnings such as
</p>
<p class="MsoNormal" style="margin: 0in 0in 10pt;">1. <span> </span>notice---: “time:0.000<span>
</span>unit:0<span> </span>type:0<span> </span>TRNSYS Message<span> </span>
90 : TRNDll.dll is compiled in release mode. External DLLs will be loaded from the .\UserLib\ReleaseDLLs\ directory.<span>
</span>Reported information<span> </span>: Not available” </p>
<p class="MsoNormal" style="margin: 0in 0in 10pt;">2. Warning---: “ time6510.500<span>
</span>unit:0<span> </span>type:0<span> </span>TRNSYS Message<span> </span>
441 : The inputs to the listed units have not converged at this timestep. The values at the last iteration will be used and the simulation will proceed.<span>
</span>Reported information<span> </span>: UNITS: 56”[ this warning repeated for 10 times]</p>
<p class="MsoNormal" style="margin: 0in 0in 10pt;">There is no any error while running for a year.
</p>
<p class="MsoListParagraph" style="margin: 0in 0in 10pt 0.5in; text-indent: -0.25in;">
<span><span>c.<span style="font: 7pt/normal "Times New Roman"; font-size-adjust: none; font-stretch: normal;">
</span></span></span>Any suggestions to tackle message 441? </p>
<p class="MsoNormal" style="margin: 0in 0in 10pt;">Thanks in advance! </p>
