Latent Heat Less than Zero (Condensation)

  Hello,
  I am seeing an error "Latent heat cannot be less than zero" is some of my cases. However, I am unable to understand the reason for this. The standard state enthalpies are correct (verified against fluent databse and external data from TEST). The hfg is indeed positive (vapour enthalpy is higher than liquid enthalpy). Not sure why Fluent is giving this error. Any insights appreciated.

  Assuming you're using the Fluent mass transfer model have you got the gas & liquid phases the right way round? I can't remember if it's to or from gas, but it's covered in the User's Guide.

  Are you defining the mass transfer from "liquid" to "Gas"?
