How can I get the surface area or volume when using VOF model?

    • FAQFAQ

      The area and volume of the liquid in the VOF model can be calculated. 

      Surface area:
      1. Create a surface for VOF = 0.5 Postprocessing -> Create -> Iso-Surface, create a Surface Of Constant Phase, Volume Fraction, and Iso Value of 0.5
      2. Run a Surface Integrals Report “Area” on the iso surface to calculate the area of the interface.

      Run a Volume Integrals Report for all fluid areas using filed variable as Volume Fraction. This will give the volume of the respected phase.

      Note: For a 2D analysis, please note that it will be calculated with a depth of 1m.
