<p>Dr. Bina,</p>
<p> There are two kinds of division by zero errors. If you're
getting one that is being reported by TRNSYS in the error/warning
log then make sure that any equations you have in your input file
are written like:</p>
<p>myEquation = 1/MAX(myVariable,0.)</p>
<p>The other kind of division by zero error is an ugly unhandled one
that comes up in a popup window over top of your online plotter.
If that is the kind that you are getting then please send the
project and any additional files needed to run it to your
distributor. They'll need to get into the code to find the cause
of the error.</p>
<p>kind regards,</p>
<p> David</p>

you so much for your reply. I finally found a way but still
does not work for the cooling condition. I made seasonally and
hourly forcing files and connected them as an input file to my
building (as you mentions in this email also). But
unfortunately for cooling give the error of division by
zero...</div>

way is using an excel file but again in the cooling does not
work and I think it is because of the zeros in the days,

<p>Dr Bina,</p>
<p> If you have access to the TESS Applications Library,
you can define such schedules using the Types in that
library. In TRNBuild you will need to select that the
schedule values will come from INPUTS instead of from
SCHEDULES that are defined inside TRNBuild.</p>
