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.

Thank You
