7.4.4.1. Buoyancy Force

There is a addition data for buoyancy force, submerged volume, Buoyant point. In addition, each geometry’s data also reported. The reference frame of all data is Inertia reference frame.

  • FM_Buoyancy: The magnitude of buoyancy force.

  • FX_Buoyancy, FY_Buoyancy, FZ_Buoyancy: Summation of buoyancy force of each geometry. Translational Force of buoyancy at Buoyant Center. The reference frame is Inertia reference frame.

    \(F_{Buoyancy}=\sum_{}^{}F_{BuoyancyGeometry}\)

  • TM_Buoyancy: The magnitude of torque.

  • TX_Buoyancy, TY_Buoyancy, TZ_Buoyancy: Summation of buoyancy torque of each geometry. The reference frame is Inertia reference frame.

    \(\tau_{Buoyancy}=\sum_{}^{}\tau_{BuoyancyGeometry}\)

  • FM_Drag: The magnitude of Drag force.

  • FX_Drag, FX_Drag, FY_Drag, FZ_Drag: Summation of drag force of each geometry. The Force of Buoyancy at Buoyant Center. The reference frame is Inertia reference frame.

    \(F_{Drag}=\sum_{}^{}F_{DragGeometry}\)

  • TM_Drag: The magnitude of torque.

  • TX_Drag, TY_Drag, TZDrag: Summation of drag force of each geometry. The reference frame is Inertia reference frame.

    \(\tau_{Drag}=\sum_{}^{}\tau_{DragGeometry}\)

  • FM_Total: The magnitude of the total force.

  • FX_Total, FY_Total, FZ_Total: Summation of buoyancy force and drag force.

    \(F_{Total}=F_{Buoyancy}+F_{Drag}\)

  • TM_Total: The magnitude of total torque.

  • TX_Total, TY_Total, TZ_Total: Summation of buoyancy torque and drag torque.

    \(\tau_{Total}=\tau_{Buoyancy}+\tau_{Drag}\)

  • Submerged_Volume: The volume of an object submerged below the surface of the water. This volume value is used to calculate buoyancy.

  • PX_Buoyancy: X position of buoyant center point.

  • PY_Buoyancy: Y position of buoyant center point.

  • PZ_Buoyancy: Z position of buoyant center point.

  • Buoyancy_geometries: Force, Submerged volume, buoyant center for each geometry.
