Hello guys,
I am new to openfoam. I read in a paper that PLIC slices and stores the end points of interface then calculates the interface length(2D) or interface area(3D). Can anyone please tell me where the interface area is stored after the interface cell is sliced by PLIC code.
It's urgent
Thanks in advance

If anyone gets same doubt You can see this.
In interface properties u can find the variable that stores interface area.
  1. Cell gradient of alpha
  2. const volVectorField gradAlpha(fvc::grad(alpha1_, "nHat"));
  3. Interpolated face-gradient of alpha
  4. surfaceVectorField gradAlphaf(fvc::interpolate(gradAlpha));
  5. Face unit interface normal
  6. surfaceVectorField nHatfv(gradAlphaf/(mag(gradAlphaf) + deltaN_));
  7. Face unit interface normal flux
  8. nHatf_ = nHatfv & Sf;
So interface area is stored in variable called nHatf_ which is a private member.
