Webscribed by its unit normal vector), while the second subscript keeps track of the direction. Each component represents a magnitude for that particular plane and direction. Figure 2: Four of the nine components of the stress tensor acting on a small ... (whereas divergence made a scalar from the vector ~v). Weboutward unit normal vector n satisfies the equation ZZ S F · n dσ = ZZZ V (∇· F) dV, where V ⊂ R3 is the region enclosed by the surface S. Remarks: I The volume integral of the divergence of a field F in a volume V in space equals the outward flux (normal flow) of F across the boundary S of V.
