Hi<div><br></div><div>There is no such a unique component in TRNSYS as far as I know. You should use Matlab type 155 component for your ANN implementation if your control system input and output are changing with time, otherwise if you want to model TRNSYS output as a ANN model you just need to export TRNSYS data to other softwares like Matlab or Python, .. to do the rest.</div><div><br></div><div>Arian<br><br><br><a href="https://overview.mail.yahoo.com/?.src=iOS">Sent from Yahoo Mail for iPhone</a><br><br><p class="yahoo-quoted-begin" style="font-size: 15px; color: #715FFA; padding-top: 15px; margin-top: 0">On Friday, October 15, 2021, 11:41 PM, ESITC Caen - mohammed-hichem.benzaama--- via TRNSYS-users <trnsys-users@lists.onebuilding.org> wrote:</p><blockquote class="iosymail"><div id="yiv1162305627"><div>

<p class="yiv1162305627x_MsoNormal"><span style="font-family:sans-serif;">Hallo everyone,</span></p>
<p class="yiv1162305627x_MsoNormal"><span style="font-family:sans-serif;"> </span></p>
<p class="yiv1162305627x_MsoNormal"><span lang="EN-GB" style="font-family:sans-serif;">I’m having a problem with the simulation of my 45-zone-model – at timestep 8,75 (0,25 h steps) the error message(s) “MULTIZONE BUILDING - SHADING RATIO OF A WINDOW IS LARGER THAN
1 OR LESS THAN 0” appears. </span></p>
<p class="yiv1162305627x_MsoNormal"><span lang="EN-GB" style="font-family:sans-serif;"> </span></p>
<p class="yiv1162305627x_MsoNormal"><span lang="EN-GB" style="font-family:sans-serif;">For all my windows I have an external shading which is an input from dck. But I don’t have a separate equation per window. I simplified the orientations to N-E-S-W have these orientations
for each zone </span><span lang="EN-GB" style="font-family:Wingdings;">à</span><span lang="EN-GB" style="font-family:sans-serif;"> means 4x45=180 shading equations. I checked the equations and the printed values – are correct – and also set it to constant
0 – still the error messages. </span></p>
<p class="yiv1162305627x_MsoNormal"><span lang="EN-GB" style="font-family:sans-serif;"> </span></p>
<p class="yiv1162305627x_MsoNormal"><span lang="EN-GB" style="font-family:sans-serif;">In an existing conversation from the archieve (“2nd error generating shading/insolation matrix -> too many shaders on projection plane”) the problem was solved by adding MIN and
MAX function to the shading equations – with this addition also the iterations in-between, not just the last iteration, have to be between 0 and 1. But I tried it and it didn’t help.</span></p>
<p class="yiv1162305627x_MsoNormal"><span lang="EN-GB" style="font-family:sans-serif;">In the same conversation a previous error was solved by reducing the surface numbers, because the surface numbers were higher than 999
</span><span lang="EN-GB" style="font-family:Wingdings;">à</span><span lang="EN-GB" style="font-family:sans-serif;"> could this be the problem? I have a quite big building with almost 1700 surfaces, especially a lot of single windows. I could simplify
the windows and combine them per wall-surface to one big window, but I want to check your expertise first.</span></p>
<p class="yiv1162305627x_MsoNormal"><span lang="EN-GB" style="font-family:sans-serif;"> </span></p>
