General Cross Section The cross section is used to model parts of the slender system with more general double symmetric geometry. The cross section is especially useful for modelling of wind turbine blades. The cross section is similar to the Double SymmetricCross Section, but can also have Mass center offset Area center offset Rotated principal axes Shear center offset Aerodynamic load center offset and rotation The input is grouped in the following tabs: Mass and Volume: mass center, mass and buoyancy Stiffness properties: area center, principal axes, shear center and the stiffness properties Damping specification: cross-sectional damping models The hydrodynamic load models available for general cross sections are: Morison’s generalized Equation No hydrodynamic loads (None option) The load model can be set in the Hydrodynamic force coefficient tab in the cross sectional properties. For details of the load models please see Hydrodynamic load models. Aerodynamic loads may also be applied. The load model can be selected in the Aerodynamic force coefficients tab of the cross section. For details of the load models please see Aerodynamic load models. Damping specification Mass and Volume
