 Make sure your free flow problem inherits from the correct parent type:

 In addition, dirichlet constraints for the dissipation or $\omega$ variable will be set for all wall adjacent cells.
 This is done in the `isDirichletCell` function, as well as the `dirichlet` function already, and requires no further changes.
