ANSYS, Inc. Release Notes
Bending stiffness may now be defined for segments of a composite catenary line when using cable dynamics.
Non-linear stiffness characteristics may now be defined for segments of a composite catenary line when using cable dynamics.
Mooring line significant tensions and spectral information at intermediate points (including the anchor) can now be reported when using cable dynamics.
A new additional stiffness matrix may now be defined to model external stiffness effects (such as mooring line) other than hydrostatic. The stiffness matrices may be associated with connections between a vessel and the ground, or between multiple vessels.
Spectral results from dynamic frequency based analyses have been extended to include:
Zero crossing period for center of gravity motions response spectrum
Velocity and acceleration response spectra and zero crossing period for center of gravity
Motions, velocity and acceleration response spectra and zero crossing period for specified nodes
ISO wind spectrum may now be selected.
New Analysis Settings. New Analysis Settings are available to control your Hydrodynamic analysis.
New Model Components have been added to the Hydrodynamic Analysis system:
Connection Points (under Geometry)
Cables and Connection Stiffness (under Connections)
Catenary Section, Catenary Buoy and Catenary Clump Weight (Under Catenary Data)
Result Graphs have been enhanced.
Hydrodynamic Diffraction Results Graphs. Diffraction, Froude-Krylov, Diffraction+Froude-Krylov, RAO, Radiation Damping and Added Mass, and Steady Drift diagrams are easier to insert into the analysis. Newly available are 3-D plots for QTF graphs, Splitting Forces, and Bending Moment/Shear Force diagrams.
New Hydrodynamic Time Response Results Graphs (Structure Position, Structure Velocity, Structure Acceleration, Structure Forces, Cable Forces, and Time Step Error) are available.
Many of the quantities shown in the Details panel can be parameterized by selecting the checkbox next to their name. These parameters will then be available to the Workbench project through the Parameter Set bar for additional post processing.
You can click on the Report Preview tab in the main window pane to generate a summary of all of the objects in your Outline. The Details information for each object appears as tables in the report. Figures and images appear as specified in the Outline. Charts that appear in the outline are also included. You have a number of options available for saving the report.
The new Hydrodynamic Time Response analysis system allows you to apply ocean environment loading (wind, wave, current) and external boundary conditions (such as moorings) to a structure, and undertake dynamic response analysis in the time domain.
The following new tree objects are available:
