“Liked” this post because of its similarity to the problem I am [working on currently](https://fenicsproject.discourse.group/t/unsure-about-vorticity-boundary-condition-in-steady-stokes-flow-past-sphere/6925): setting a far-field boundary condition to be zero in a coupled PDE system returns the trivial result for that variable.

Eagerly watching the space for any help/insight.

Thank You  
Warm Regards
