<p>Dear TRNSYS-users,</p>
<p><br>
</p>
<p>like some other members of this list before, I am having trouble generating a shading matrix for a multizone building model. The model is quite complex 70 zones, 995 surfaces.
<br>
</p>
<p><br>
</p>
<p>With the attached 3D-Model I can create a deck in Simulation Studio and succesfully run simulations but as I try to generate a shading/insulation matrix in TNRBulid the answer is:
<br>
</p>
<p>"forrtl: severe (41): insufficient virtual memory ..."<br>
</p>
<p><br>
</p>
<p>I read everything I could find in the archive of this list and tried to solve the problem myself but did not succeed yet. I would apprechiate if some more expericenced user could take a look at my attached files and maybe find the reason why it does not
work or give me more detailed advice how to debug the model.</p>
<p><br>
</p>
<p>I attached the *.idf file and a *.b18 file <br>
The windows I used in the model can be found in the w4-lib.dat<br>
</p>
<p><br>
</p>
<p>Here is what I did by now:</p>
<p><br>
</p>
<p>I made the model this complex in order to show the divergence between simplified and more detailed building models in my research so simplifiying the model is not the first move I want to make to solve the problem.</p>
<p>- Reducing the complexity of the shading geometry up to no shading geometry at all ->same error</p>
<p>- Setting all airnoes' longwave radiation model to "simple model" </p>
<p>- Using a different version of sketchup to create the *.idf - file</p>
<p>- Importing the *.idf-file directly into Simulation Studio or directly into TRNBuild
<br>
</p>
<p>- set SHM_MODE=1 in the *.idf file before importing</p>
<p><br>
</p>
<p>Thank you in advance for your help,</p>
<p><br>
