Is there any mathematical tool or other efficient way to transform from component form to vector form of partial differential equation?

In the field of solid mechanics, Navier’s partial differential equation of linear elasticity for material in vector form is: (λ+G)∇(∇⋅f) + G∇2f = 0, where f = (u, v, w) The corresponding...
