Hello,

I'm using EnergyPlusDLL 2.1.0.023

Here are my errors :

Does anybody got ideas?

Could-you translate what means this words for DB:

-Time Steps in hour (I've already tried to change it without result!)
-GroundTempératures (Its my external conditions, I can't change it)
-FullExterior or FullInteriorExterior (It's so confused for me)
-Température out of bounds (Do I need to redefine boundaries?)
-no thermal mass (Talk about inertia?)
-Regular-R (???)

Could you post your dsb file so we can look into why you have 'temperature out of bounds errors'?

The simulation is failing because of the 2 large parapet zones on top of the buildings with '100% hole' in the roof. I think you have modelled it this way to get the effect of shading from the roof parapets. The problem is that a zone is formed and the surfaces of these zones are getting too hot in the simulation when solar radiation is incident.

A better way to do this is to delete the top blocks and replace the parapet walls with component blocks to give shading.

See attached screenshot.

It works better. Many errors for this!

Many thanks

Could you take of my file.

Thanks
