I set volume fraction of h20 to 0.005, o2 to 0.228 and rest is n2.  The densities of the substance are constant and the possibility of condensation has not been enabled. 

  1. When i use same BC but operating density ,,minimum average phase" for expamle contour of velocity are as image 1 and residual image 2.
  2. But when i use ,,mixture average density" solutions are different (image 3, and 4)
  3. As you can see The results are so different that they destroy the whole simulation.
