Error Related to DOE-2 Simulation

[cb455]

Every time I attempt to analyze my model, Insight always responds with this: 

Detailed status:

Model: Chelsea Project Energy Analysis 2

Location: 733 Eastern Pkwy, Crown Heights, NY

Error: Issue: An error has occurred related to the DOE-2 simulation. It is below and may be of assistance in determining the issue with your building model. <br/> *16847* ..<br/>*ERROR****************************************************************************************

Two VERTICES are identical <br/> *16848* $aim21595_dep_3_N_Shade_sp-None<br/>

I have tried adjust my model, and the Revit coordinates, but it still doesn't work. Could someone help me?

Hi @cb455 

did you try to run your model with the Next Generation of Insight, instead of Insight/GBS?

Best,

I am currently using Revit 2025.3 which has the Insight plugin already. I've used the Carbon Insight function, and it works. But when I used the Energy Optimization, It fails. Is there another Insight version?

Nevermind. I just had to copy the model over into a new project file, and now it is working. Thank you for you help Guiseppe.
