The Incident Velocity Potential subnode is available from the context menu (right-click the
Plane Wave Radiation parent node) or from the
Physics toolbar,
Attributes menu. Use this to add a velocity potential and wave direction.
Enter a Velocity potential φ0 (SI unit: m
2/s) and
Wave direction ek (SI unit: m). The default for the wave direction is the inward normal direction of the boundary.
