Detailed Description

Assemble non-linear part of the velocity component of the RHS vector.

Operator for assembling non-linear part of the velocity component of the RHS vector:

\[ \mathbf{R}^{\textrm{NS}}_{\mathbf{u}} = C_\text{I}\int\limits_\Omega \left(\mathbf{u}\cdot\nabla\right)\mathbf{u} \cdot\mathbf{v} \,d\Omega, \]

where \(C_\text{I}\) is the inertia coefficient: \(C_\text{V}=\rho\) in the dimensional case and \(C_\text{V}=\mathcal{R}\) in the non-dimensional case.
