This model implements a single-phase, isothermal Navier-Stokes model, solving the  momentum balance equation     
\[\frac{\partial (\varrho \textbf{v})}{\partial t} + \nabla \cdot (\varrho \textbf{v} \textbf{v}^{\text{T}}) = \nabla \cdot (\mu (\nabla \textbf{v} + \nabla \textbf{v}^{\text{T}}))
  - \nabla p + \varrho \textbf{g} - \textbf{f}
\]
 By setting the runtime parameter Problem.EnableInertiaTerms to false the Stokes equation can be solved. In this case the term   
\[     \nabla \cdot (\varrho \textbf{v} \textbf{v}^{\text{T}})
\]
 is neglected.
The  mass balance equation    
\[      \frac{\partial \varrho}{\partial t} + \nabla \cdot (\varrho \textbf{v}) - q = 0
\]
closes the system.
