Eulerian multiphase model

      Hello, 


      I have a previous post about using the Eulerian model for a model of the air-sea interface. I am looking further into the Eulerian model and it seems that the secondary phase has to be particles (i.e. bubbles or droplets). I also see when setting the second phase that it requires a diameter size. I was trying to add my second phase (water) as half of the domain while the other half was moist air. When trying to do this I kept encountering initialization errors. Is this because the model does not work with large amounts of the second phase?


      Thanks,


      Alex

      The model does work with large amount of secondary phase. You can understand the diameter for a secondary phase which is morphologically continuous as sort of interfacial length scale which might affect drag and interfacial area.


      If you true separated phases I will activate MultiFluid VOF and use at first symmetric drag model. Please keep phase diameter to default and use interfacial area as gradient based

      Thank you, I will try this.
