Highlights of the capabilities
- Orientation of floating bodies defined using “Tait-Bryan” angles (convention similar to that used by NASA).
- 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.
- 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.
- Ability to import models in MOSES & SACS formats and 3D bodies in IGES format.
- Compute-intensive calculations run on multiple processors.
Upend
- Analysis of free floating condition, 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
