Model creation can be performed through Ansys DesignModeler software or via other Ansys structural mechanics tools using a provided Ansys APDL macro. These include SPARs, FPSOs, Semi-submersibles, Tension leg platforms, Ships, Renewable energy devices, and Breakwaters.Īqwa has been used extensively in the oil & gas, renewable and general engineering sectors to model installation and use of equipment in open water as well as in harbors or sheltered locations.Īnsys Aqwa Diffraction is a boundary element method (BEM) solver that provides an integrated facility for developing primary hydrodynamic parameters required to undertake complex motions and response analysis. 218–227 (2010).Ansys Aqwa software addresses the vast majority of analysis requirements associated with hydrodynamic assessment of all types of offshore and marine structures.

Turbine centerline flow velocity versus downstream distance as predicted by the Delft3D simulation (green) against the measured data from the canal (blue dots).įigure 3 further illustrates the turbine wake characteristics, by showing the centerline turbine wake velocity versus downstream distance. Delft3D was developed by the Dutch company, Deltares.īecause it is actively developed and maintained and because it is held in high regard by researchers and practitioners alike, Sandia is developing Delft3D as a complementary replacement for the aging open-source-version of the Environmental Fluid Dynamics Code (EFDC), which was modified to include a current energy converter (CEC) module and renamed SNL-EFDC.įigure 3. Sandia Modifies Delft3D Turbine Model J11:28 pm Published by Adminĭelft3D is a state-of-the-art, open-source hydrodynamics software suite capable of modeling hydrodynamics, sediment transport, and water quality in rivers, lakes, estuaries, and coastal environments.
