Define a stream with required composition.
Then set specification either to "Temperature and vapour fraction TVF" or "Pressure and vapour fraction PVF".
Define vapour fraction to 0 or 1. This will calculate the bubble / dew point.

I have a hyrocarbon stream. How can i find its dew point and bubble point at given temperature and pressure by using DWSIM.
