External fluid field point element. This element gives the pressure head amplitude at a specified point in the external fluid domain. When the element is at the water surface, it corresponds to the amplitude of the water surface elevation. Only applicable in Aqwa-Line with a radiation/diffraction analysis is run. If a hydrodynamic database is imported from a previous run it is not possible to calculate the water surface elevation.

FPNT elements are defined in the LSA axes and move with the structure in which they are defined.

FPNT elements are subject to symmetry commands.
