Just a quick note to highlight that we have now merged into Master a branch for high order outflow boundary condition on the incompressible Navier Stokes problems. This merge now supports the “convective like” outflow conditions proposed by Steve Dong (JCP 2015). It also allows for a slightly modified version of the velocity correction scheme where we formulate the pressure as a weak problem rather than starting from the strong form of the pressure Poisson problem. This is also consistent with the work of Guermond & Shen on these scheme. I have tried to motivate both of these modifications by restructuring the description of the method in the user guide. 

Cheers,

Spencer.
