  Greetings
  
  Respected experts I hope you are in good health. I am a researcher working on nucleation of a bubble in a super heated domain.
  
  First of my question is about the area of a face and volume of a cell in 2d Domain. As it is mentioned in fluent manual that F_AREA(A,f,t) return face area vector of a given face in a face thread.
  
  So in order to get area of that face NV_MAG(A) should be used. Can you tell me that it is right?
  
  If there are two phases in a cell and if some one applies (C_VOF_G(c,tp)[0]+C_VOF_G(c,tp)[1] ) so would it presents interface area between two phases for free surface modelling
  
  Pardon if the question are not really mature but I am new to fluent and in slight confusion about this.
  
  Thank You

  Assuming 2d planar nv_mag of area vector to get the face area.

  Second question that is wrong. You need the magnitude of the gradient.

  To your first reply if we have a 2d planer Domain. Then what would be the difference between the volume and area. Can you elaborate it more.
  
  Yes that would be the magnitude for your second reply but how to get magnitude I mean which macro we can utilize??
  
  Thank You
