EcoDesigner Star - zone calculation not converging

Not applicable

Until now my energy simulations has been running smooth on this project. Now after about 2-3h of simulation it fails with the error ID 139 "zone calculation do not converge".

I have no clue what is causing this. Is there no detailed report on the error that I can find? Any ideas?

I did some digging and that error seems like something that can't be solved with simple suggestions. I would suggest you to contact your local support so that they can analyze the project and see which element/setting might be the source of the problem.
