OtisChen New Member Cheng CHEN Join Date: Jun 2020 Posts: 8 Rep Power: 5	Hi all I want to know where the mass sources will be added in a liquid-gas two phase flow when VOF model is used? In my case, there is a surfactant in the liquid that is similar to ethanol. -- If you have only one species in your problem, you can simply define a Mass source for that species. The units for the mass source are . In the continuity equation (Equation 1–1 in the Theory Guide), the defined mass source will appear in the Sm term. -- Above is from the ANSYS help ,so the species refers to the liquid/gas, or to the surfactant I have added. Best regards cheng chen
