Hi!

I want to use aqwa and rigid dynamics to simulate a wave energy converter.  I wonder if there are some tutorials about this co-simulation available? The description in aqwa is too concise. Thank you!

Hello,

I'm afraid the training material for the Aqwa-Rigid Dynamics cosimulation has not been published yet, however the online documentation provides a description. This is contained in Section 8.3 of the Aqwa User's Manual, which you should be able to access from the Aqwa Workbench editor by clicking Help > Workbench User's Manual.

Hi,

Thank you. Is there any training material for co-simulation under preparation? If so, when it will be available?

Hi Xinyuan,

The training material exists in draft state, so it shouldn't be too long before it is published... but I can't give you an exact date, I'm afraid.

If you have a customer account, you could try creating a Service Request to ask for the material directly from the Aqwa development team.

Cheers, Mike

Hi

i also use aqwa co simulation for simulating floating offshore wind turbine and in the aqwa co simulation setup in ansys rigid dynamic module i have a big problem with uploading the Aero Dyn primary input file and inflow wind input file , it does not work and in extension log file some erorre appear like this :

AqwaCosimulation: Inadequate blade data files (ADBlFile) given in the AeroDyn primary input file (C:\Users\fatemeh.km\Desktop\AeroDyn primary input file.txt)
AqwaCosimulation: Failed to prepare the AeroDyn marker data.

......can you send a  Aero Dyn primary input file sample for me ?

this is my Email :abnmohaen@gmail.com

Hello,

Unfortunately as an Ansys employee I am not able to share anything with you through this forum, hopefully someone else can help you out with this. However, I can suggest that your AeroDyn input file may be missing some key lines like:

======  Rotor/Blade Properties  ========================
True          UseBlCm            - Include aerodynamic pitching moment in calculations?  (flag)
"BladeData.dat"    ADBlFile(1)        - Name of file containing distributed aerodynamic properties for Blade #1 (-)
"BladeData.dat"    ADBlFile(2)        - Name of file containing distributed aerodynamic properties for Blade #2 (-) [unused if NumBl < 2]
"BladeData.dat"    ADBlFile(3)        - Name of file containing distributed aerodynamic properties for Blade #3 (-) [unused if NumBl < 3]

The number of entries should match the number of blades (3 in this example). I hope this helps.

Mike
