I used compute pair/gran/local in order to find the contact area between two superquadrics. The output gives me 260 mm^2 while the diameter of the particles is 11 mm. The contact is edge-face, so basically this small overlap between face and edge, according to the output, produced the contact area more than twice the face-to-face total contact between the particles.
The question is what does "contactArea" exactly represent? What are the possible reasons why the contactArea found is so large?
Thanks everybody for Your replies in advance!
