Air as a Component

Q1, in case the error is that no surface tension correlation is available for air, there are several ways to resolve this. You could remove surface tension from your property packages (from the properties tab), or you could change the pure surface tension method to "Compound defined" rather than "Temperature correlation". In this case the selection can be made per compound from the Compounds tab. This defaults to "Temperature correlation" for the compounds for which a temperature correlation is available. For air, a different default will be selected (Brock & Bird).
