Apache Error during simulation

[vmolluzzo]

Hello,
I am brand new to IES and encountered an error running a file that says "Unexpected end of HVAC network file." I checked the network in ApacheHVAC and it is telling me its fine. What else could be the cause of the error?
Thank you

This error usually occurs when a system has no rooms assigned to it or when an HVAC file is empty (has no systems at all). The network configuration of the HVAC file may be okay, but that doesn't mean it is properly assigned to the building. I suggest checking your multiplexes and ensuring that each layer is assigned to a valid room in the model.
