The boundary condition \(u=0\) makes \(u\) change sign at the boundary, while the condition \(u_x=0\) perfectly reflects the wave, see a web page or a movie file for demonstration. Our next task is to explain how to implement the boundary condition \(u_x=0\), which is more complicated to express numerically and also …

Global linear stability analysis of open flows in truncated domains suffers from imperfect boundary conditions, leading to either spurious wave reflections (in compressible cases) or to non-local feedback due to the elliptic nature of the pressure equation (in incompressible cases). A novel approach is introduced to solve such an issue.
