V2020.1 Release Notes - Hydrodynamic Data Importer |
|
•The Hydrodynamic Data Importer is a very helpful utility program from our software suite now available with PipeLay Version 2020.1. It allows you to automatically import characteristic data, in terms of displacements RAOs relating to a vessel from a range of well-known hydrodynamic simulation packages, including WAMIT, ANSYS Aqwa and NEMOH.
•While the data relevant for PipeLay are the displacement RAOs, the Hydrodynamic Data Importer can also convert force RAOs in a similar manner and other floating body properties, such as:
oHydrodynamic Stiffness – used to model the effects of buoyancy on the floating body
oAdded Mass, Radiation Damping – used for wave radiation loads
oNewman’s Quadratic Transfer Function – used to derive second-order wave drift loads.
•PipeLay, like most other programs, has its own set of conventions regarding the specification of input data. The importer understands the output file formats and conventions used in several third-party software packages, and can automatically read in the relevant input data, perform the necessary conversions, and create output files which are readily accessible by PipeLay.
•The Hydrodynamic Data Importer was developed in-house by our engineers. This has enabled our engineers to perform more simulations by reducing the time spent converting data and avoiding errors that can occur during a manual conversion.
