Hi superjer,

Thank you for your interest, those two function are used to accelerate the successive substitution method (used in flash, bubble and dew point calculations). The the gdem method uses two eigenvalues for the acceleration and the dem function uses one. More details can be found in the original publication from Crowe and Nishio (1975).

I hope that helps.
