Hi all

I found the following piece of code in order to calculate surface area of the free surface in interFoam.

volScalarField gradGamma
= mag(fvc::grad(gamma));
scalar totalSurfaceArea
= sum(gradGamma.internalField()*mesh.V());

Can somebody please elaborate on it. I mean the physics part as I understand what this code is doing.

Thanks in advance

Regards
Jaswinder
