Скачать или смотреть Numerical simulation of complex mooring lines with DualSPHysics (SPH on GPU)

DualSPHysics has been coupled with the MoorDyn library.

MoorDyn is a lumped-mass mooring line model designed for easy coupling with other software (i.e. floating platform models). It supports arbitrary line interconnections, clump weights and floats, and different line properties. The model accounts for internal axial stiffness and damping forces, weight and buoyancy forces, hydrodynamic forces from Morison’s equation, and vertical spring-damper forces from contact with the seabed.
It has been developed by Matt Hall (University of Prince Edward Island, Canada). More information and downloads can be found at www.matt-hall.ca/software/moordyn.

This working example shows a complex layout where a box is moored to a float that is also connected to four mooring lines. The box moves due an external acceleration of 0.5 m/s^2 applied to the fluid. The buoyancy-driven motion of the box leads to the drag of the mooring system.
