Double Symmetric Cross Section The cross section is used to model bi-symmetric parts of the slender system. The cross section is similar to the AxisymmetricCrossSection, but can have different stiffness properties and load coefficients in / around the two local axes. The hydrodynamic load models Morison’s generalized Equation Morison partly submerged cross sections MacCamy Fuchs Potential flow No hydrodynamic loads are available for Double Symmetric Cross Sections.
