TRNBuild/Type56 will allow you to set the boundary temperature
either as a "identical" or as a constant, an input, or a schedule.
You want to select "userdefined" then click on the little arrow
button to the left of the constant boundary temperature that pops
up. Change from "constant" to "input." Go back to the Simulation
Studio, right click on Type56 and tell it to update the input list.
Once it does, you should see your the boundary temperature as an
input. Read in your measured boundary temperature using type9 and
pass the appropriate output to Type56.<br>

<title>Use of a varying boundary wall temperature profile - (Paul
O Sullivan)</title>
<!-- Converted from text/plain format -->
<p><font size="2">Hi TRNSYS Users.<br>
<br>
I am trying to establish if it is possible to use a measured
temperature profile as the specified boundary condition for an
internal boundary wall. I am measuring surface temperatures on
both sides of the internal walls of the single room being used
to validate a TRNSYS model. This means I could consider using
this data as the boundary condition for these walls instead of
modelling adjacent spaces to the room of interest. Does
TRNBUILD only accept a single value for this condition or is
there a way to apply a time varying boundary condition.
Alternatively I can use an average over the period of analysis
but this will give some inaccuracy to the model.<br>
<br>
Thanks for your help. !<br>
