Introduction to ANSYS Aqwa

Date May 29, 2013 - May 31, 2013 (3 days)

The Netherlands, Infinite (Breda)


ANSYS Aqwa Training Course

The course will cover the general use of features within the Aqwa Suite and introduce the new Workbench version of Aqwa.  An introduction to the expanded Cable Dynamics capabilities will also be included.  The latter is licensed as an additional module and permits coupled cable dynamics associated with deeper waters to be addressed.


Topics covered include:


  • Geometry modelling
  • 3D wave diffraction/radiation analysis
  • Static and dynamic (oscillatory) equilibrium and stability analysis
  • Frequency domain analysis. Significant motions and tensions for the system due to wave frequency and/or drift frequency excitation. Wave frequency RAOs for uncoupled/coupled moored structures
  • Non-linear analysis in time domain (regular waves) for a moored structure with and without Cable Dynamics
  • Linear time domain analyses in irregular waves for a moored structure with and without Cable Dynamics. 
  • Mesh generation, model visualisation, animation, post processing, graphing, analysis functions and Cable Dynamics
  • Other constraints such as fenders and articulations
  • Multi-body hydrodynamic interaction
  • Parametrics
  • Load mapping of pressures and motions to ANSYS Mechanical




The three day course will be of major benefit to all engineers intending to perform hydrodynamic analysis of offshore structures using Aqwa. No previous Aqwa exposure is required but some knowledge of naval architecture or offshore engineering is desirable.


The lectures are interspersed with "Hands on Sessions" that demonstrate the application of each of the modules.

For private courses we recommend a maximum of six attendees.
