*BEAM FLUID INERTIA
Define additional beam inertia due to immersion in a fluid.

This option is used in conjunction with the *BEAM SECTION or *BEAM GENERAL SECTION option to include added inertia effects in Timoshenko beam elements due to immersion in an inviscid fluid.

Optional, mutually exclusive parameters: 

FULL

Use this parameter to specify a fully submerged beam (default).

HALF

Use this parameter to specify a half-submerged beam.

Data line to define beam fluid inertia: 

First (and only) line:

  1. Mass density of fluid.

  2. Local 1-coordinate of the center of the cylindrical cross-section with respect to the beam cross-section, x.

  3. Local 2-coordinate of the center of the cylindrical cross-section with respect to the beam cross-section, y.

  4. Radius of the cylindrical cross-section, r.

  5. Added mass coefficient, (default = 1.0), for lateral motions of the beam.

  6. Added mass coefficient, (default = 0.0), for motions along the axis of the beam. This coefficient affects only the term added to the free end(s) of the beam.
