Species model

      Hello,


      I`m using the species model for describing the mass transfer from water liquid to vapour in a mixture of air (evaporation-condensation problem) in a closed volume. For the moment I`ve selected in the species model only "species transport". I think that the reaction are not needed but I don`t know what are the voices under "options".


      Are important for describing my problem? (sorry but in the user`s guide I don`t have found an answer)


      Thank you

      No, in this case you just need a mixture. If you click on help on the panel the other options should be explained, and no, you don't need to select any of them: you can probably deselect Diffusion Energy Source too. 


      I assume you've already set the phases up? 


       


      Edit: moving to Fluids too

      Thank you! Yes I`ve set water liquid for the primary phase and the second phase is mixture.
