1. The simulation has not run correctly because of this severe error: **
** ** Severe ** CheckWarmupConvergence: Loads Initialization, Zone=“E1” did not converge after 25 warmup days.

Hello,

I am trying to simulate a courtyard typology with 32 zones involves. As soon as I try to connect the natural ventilation component, it starts producing the above mentioned error. Please find enclosed images . I hope you could help.

Thanks.

I took a look at the file. It’s a complex file and needs simplification before someone can take a look. Kindly go through these guidelines and re-share a simplified version of the file please.

Hi Devang,

I went through the guidelines and simplified the file into 5 parts; geometry, profiles, internal loads, hvac/natvent and run simulation. I also internalized the geometry for ease and marked the boolean toggles to be made true. I hope it becomes understandable.

I also came across this other post from the forum, but didn’t seem to help the problem. (WarmupConvergence)

I also tried increasing the warmup days using simulation control, energy sim parameters components.
