Workaround for Fatal Pump Error in CBECC-Com v3c
I'm getting the following fatal error in EP after running a v3 CBECC-Com model (generated from IES VE) in v3c.
** Fatal ** ManagePumps: Invalid PumpIndex passed=3, Pump name={2F8F93D1-99C6-4687-8A38-3D2977F628F6}, stored Pump Name for that index=PUMP HWCP-1
It appears that the Pump object Name field is being replaced with a UUID from a Node causing a fatal error in EP here (see => below).

Have you got an XML file to share? Or an adjusted one if there are details that can't be shared? Is this a pump in the baseline or proposed? What does the pump serve?
@pflaumingo updated with link to XML. I deleted the offending pump and am running it again to see if it's more of a soft bug.
Is it a SHW pump?
Yes in the proposed
apmodel. Perhaps I'm breaking a T24 rule?For a properly defined/working model, the only pump that should have a UID name is circulation pump on SHW loops. If you can't post the file here, I recommend submitting this as a CBECC-Com issue for further review.
