These are some common issues faced by MachLine users

Zero surface velocity and constant surface pressure in results when using the Morino formulation

This has likely arisen from the mesh being generated inside-out. MachLine expects the panels to be oriented in such a way that the normal vectors point outward from the mesh. If the normal vectors point inward, then MachLine will attempt to force zero perturbation potential outside of the body, meaning your resulting velocities will be zero. To fix this, the mesh needs to be fixed.
