Temperature Solver cannot converge error in ITA 941

Hi Team,

I am getting this error " Temperature Solver cannot converge.Temperature values may not be accurate" in ITA 941 when running 3D in measure and calculated plane. Any suggention on how to resolve this?

Thanks,

Romeo

Hello Romeo, there can be a number of reasons the temp solver can have difficulties with the room calculation. There are a few comments made on this community page.

Looking at your screenshot, I'd ask if the racks in the lower corners are empty or do any of your racks have 0 estimated load? That scenario can cause problems with the cooling solver. Is the only cooling for this solution the in-rows in the containment system?

Hi Greg,

Yes there are racks that are empty or 0 load. This Data center is only running on 4 inrow systems.

Thanks,

Hello Romeo. I didn't notice at first, but make sure your hot aisle contain also contains the racks/objects on each side. I pasted an example below. So in your case widen the containment system so your racks/inrows are inside, see how the exits from my below example are as wide as the containment row plus the two rows containing the racks and inrow.
