      SYMPTOM: In Vista_CCD, the semi-perfect gas option is disabled. PROBLEM: The model fails to work correctly. WORKAROUND: If the ideal gas option is not sufficient for the case, the real gas option is still available. The intention of the semi-perfect gas option was to provide a more accurate solution than the ideal gas option provides for air and nitrogen, by allowing the ratio of specific heats to vary with temperature. The semi-perfect gas option is typically only useful when working with air compressors of very high pressure ratio, for example 9:1. FIXED IN: ANSYS Release 14.0.
