KNOWN ISSUE: Incorrect use of gas constant in NES nucleation model (Class 3 Error)

When using the non-equilibrium steam model, the amount of nucleation predicted by the model is in error, and therefore incorrect results are obtained.

The nucleation model incorrectly uses the universal gas constant rather than the gas-specific gas constant. As a consequence of this error, the bulk tension factor specified by the user is often changed - this is no longer required in corrected software.

No workaround is currently available.
