CABLE SOLUTION Simulation capabilities

Body Effects:

Hydrodynamic drag with angle-of-attack effects Inertial mass and moment of inertia,added mass, buoyancy

Thruster force - Parametric or independent Offset centers of pressures, gravity, and force.

Collision and inter-body, body/ground friction.

Surface interaction (buoyancy effects, drag effects)

Towpoint Effects: Parametric or input-file based position and velocity curves in X- and Y-positions

Cable Effects:

Elasticity or Bending Stiffness, structural damping, hysterysis

Axial Vibration, Hydrodynamic drag with angle-of-attack effects

Inertial Mass and Moment of Inertia, Added Mass, buoyancy Collision, friction Surface interaction (buoyancy effects, drag effects)

CABLE SOLUTION is designed to accurately simulate the following phenomena:
