<p class="MsoNormal">Hi Patrick,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have been to this a month back for one of my project. Further analyzing it in simulation output report says that it happened because of convergence error.
<o:p></o:p></p>
<p class="MsoNormal">I dig a bit more in quality control reporting under tools shows that the ratio for occupancy to fan schedules 0.00.
<o:p></o:p></p>
<p class="MsoNormal">I went back to one of my saved model in which I did not assigned the schedules and HVAC capacities, rectified my schedules and capacities again.<o:p></o:p></p>
<p class="MsoNormal">That reduce my modelling time form 30 min to 2 min approximately.
<o:p></o:p></p>
<p class="MsoNormal">The error in the below image were not available in simulation output file after every simulation, i checked it n number of times and then finally I got issue in my model.
<o:p></o:p></p>
<p class="MsoNormal">Hope this will help!<o:p></o:p></p>

<p class="MsoNormal"><span lang="FR-CA">Hi everyone,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="FR-CA"> <o:p></o:p></span></p>
<p class="MsoNormal">One of my recent models on DOE 2.3, with VRF, take much longer to run (~30min) than what eQUEST takes normally.<span lang="FR-CA"><o:p></o:p></span></p>
<p class="MsoNormal">The calculation time isn’t that long compared to EnergyPlus, but eQUEST has a tendancy to “completely freeze” the computer while the calculation is going… which is kind of troublesome.<span lang="FR-CA"><o:p></o:p></span></p>
<p class="MsoNormal"> <span lang="FR-CA"><o:p></o:p></span></p>
<p class="MsoNormal">Has anyone noticed the same thing? I’m wondering if it has to do with the VRF calculations.<span lang="FR-CA"><o:p></o:p></span></p>
<p class="MsoNormal"> <span lang="FR-CA"><o:p></o:p></span></p>
