[Bug] Pressure-Enthalpy Flash with CAPE-OPEN Property Package fail for some Operation Units #155

Describe the bug Some Unit operations cannot perform a PH flash to calculate the outlet temperature because outlet enthalpy is NaN. So far, I replicated this issue in a valve, cooler, and compressor. I'm using a property package created externally and proved in other process simulators like COCO. The problem appears when the stream is vapor only.

@byryepez please re-download the 6.5.3 installer, which contains this fix.

Thanks @DanWBR. Reinstalling the newer 6.5.3 installer fixed the issue.
