ANSYS, Inc. Release Notes
The non-linear axial stiffness definition of the dynamic cable has been extended to the quasi-static elastic composite catenary cable. The non-linear axial stiffness of each section of a quasi-static composite line can be defined in the same manner as in the dynamic cable case.
The second order force/moment calculation related to any specified wave spectrum can be optionally switched off by a new data record NODR in Data Category13 (SPEC).
Results from the hydrodynamic diffraction analysis can be generated in a text file format to use for ocean wave loading in Mechanical APDL analyses. This can be achieved by running the AQWA2NEUT program after the hydrodynamic diffraction analysis.
The AQWA Reference Manual is now accessible from the ANSYS Help Viewer.
Gaussian wave spectrum is now available for the main spectrum in addition to a cross-swell spectrum. Gaussian is available as a Wave Type for the Irregular Wave object in a Hydrodynamic analysis in Workbench.
Multiple directional spectra are now available in core AQWA-LIBRIUM and DRIFT, and the Hydrodynamic Time Response system in Workbench (implemented as the Irregular Wave Group). 2nd order interaction between different directions is included in the core applications only. This effectively allows spreading in AQWA-DRIFT.
Linearized Morison drag on TUBE elements has been added to AQWA-LINE. When AQWA-LINE stage 5 is run with a new LDRG option a set of modified RAOs is calculated and written out to the .LIS and .PLT files. Linearized Tube Drag is also available as an Analysis Settings option in the Workbench Hydrodynamic Diffraction system.
Two new capabilities have been added to allow the distribution of bending moment and shear force down a truss spar structure to be plotted in the AGS. See the AGS Help (Start > All Programs > ANSYS 14.0 > Help > AQWA > AGS Help 14.0) for more information.
Wheeler stretching has been introduced for the calculation of wave pressure in AQWA-NAUT (WHLS option).
New Model Components have been added to the Hydrodynamic Analysis system:
Fenders (under Connections)
Joints (under Connections)
Connection Points (under Parts), which allow Connection Points to be defined on structures
Revised Model Components for the Hydrodynamic Analysis system:
Fixed Points (under Geometry) have the same behavior as Connection Points did in the previous release
Result Graphs have been enhanced.
Linearized Tube Drag Forces, as an individual graph or included in the reporting of total forces, are available for Hydrodynamic Diffraction Results
Fender Forces and Joint Forces graphs are available for Hydrodynamic Time Response Results
