  6: \begin{align*}
  7:   (\nabla v, \mu (\nabla u + {\nabla u}^T)) - (\nabla\cdot v, p) + (v, f) &= 0 \\
  8:   (q, \nabla\cdot u)                                                      &= 0
  9: \end{align*}
 10: Free slip conditions for velocity are enforced on every wall. The pressure is constrained to have zero integral over the domain.
