Highlights of the capabilities
Analysis capabilities: Mooring, Stability (AKG), Floatation, Upend, Multi-body Statics & Dynamics.
Real time 3D visualization of simulation. Ability to pan-zoom-orbit while the simulation is underway.
Compute-intensive calculations run on multiple processors.
Ability to import models in MOSES & SACS formats and 3D bodies in IGES format.
Uses two completely independent approaches—energy minimization (Nelder-Mead Simplex) & force balance approach (Newton), to determine equilibrium state.
Newton’s solution for equilibrium uses exact stiffness matrix for hydrostatics and connected elastic catenaries which is necessary for second-order convergence.
Orientation of floating bodies defined using “Tait-Bryan” angles (convention similar to that used by NASA).
Upend
Analysis of free floating condition and energy contour plots
Upend analysis with given sequence of hook load, hook height, and tank flooding
Structural loads for given time steps (self-balancing)
Mooring
Multi-segmented mooring lines with clump weights and buoys
Exact governing equations for elastic catenary
Solution of multi-segmented elastic catenary using classical Newton’s method with exact linearization
Multi-body analysis
Multi-body static and dynamic analysis
Airy, Stokes-V, and Stream/Fourier wave theories, Current
Uses 4th order Runge-Kutta approach for dynamic analysis
