Detailed Description

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

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

\[ \mathbf{R}^{\textrm{S}}_{\mathbf{u}} = C_\text{V}\int\limits_{\Omega}\nabla\mathbf{u}\mathbin{:}\nabla\mathbf{v}\, d\Omega \]

where \(C_\text{V}\) is the viscosity coefficient: \(C_\text{V}=\mu\) in the dimensional case and \(C_\text{V}=1\) in the non-dimensional case.
