Minutes from the AeroDyn Overhaul Kick Off Meeting

Postby Jason.Jonkman » Fri Feb 22, 2008 4:17 pm

Dear Wind Turbine Aerodynamics Modeling Enthusiast,

The AeroDyn overhaul kick off meeting took place on Wednesday and Thursday, February 13 and 14 at the National Renewable Energy Laboratory in Colorado. The presentations given at the meeting, as well as the meeting minutes, are available at http://wind.nrel.gov/public/jjonkman/Ae ... OffMeeting.

The meeting was a tremendous success, with great discussion and feedback. Fifty attendees participating in total, both in person and through a net meeting. Thank you to everyone who participated. I hope that those who travelled to Colorado made it back home safely and that those who attended through the net meeting found the format acceptable.

We've established this forum for ongoing communication and feedback regarding the AeroDyn development project. Everyone who is interested should subscribe to this and every topic they want to follow or contribute to. (To do this, go to the page for the topic and click on "Watch this topic for replies" on the bottom left of the page.) We will periodically post updates on our progress and ask for feedback when needed. Please feel free to post your own comments at any time.

We hope that our efforts will result in an improved set of aerodynamic routines that are beneficial to the wind turbine community.

Best regards,

Jason Jonkman

CFD and Advanced Wake Models topics

Postby Marshall.Buhl » Mon Apr 07, 2008 4:12 pm

I added two new topics called "CFD" and "Advanced Wake Models," so you may want to go to those topics and click on the "Watch this topic for replies" links in the lower-left of each forum page if they interest you.

Hi,

I added a new forum topic for discussing advanced computation techniques. Please request notification of postings if it interests you. To do that, go to that topic and click on the link that says "Watch this topic for replies."

Hi Marshall,

New suggested topic (Developing AeroDyn for Vertical Axis Wind Turbine)

Please let me know if the AeroDyn is developed for vertical axis wind turbines(VAWT), or no?

It will be so nice to give information in coupled dynamics modeling analysis of VAWT in NREL or elsewhere?

THX

Dear Gurhan,

NREL has not done much recently with vertical-axis wind turbines (VAWTs) and does not currently supply software for VAWTs.

However, Sandia National Laboratory in the US has developed the OWENS code for floating VAWT analysis. I’m not sure if it is publicly available, but I believe that was the intent. More information may be found here: http://energy.sandia.gov/energy/renewab ... ne-rotors/.

GH-Bladed

Postby Mina.Ghassempour » Tue Mar 30, 2021 5:22 am

Hello,
I am using GH-BLADED or modelling Phase IV of OC3 (5MW floating Offshore wind Turbine with Spar support_structure), my question is this, does anyone used GH-BLADED for simulating this model, because I implement the model as exactly as the file of Definition of the Floating System for Phase IV of OC3,J. Jonkman, but the analysis can not be run for more than a few seconds: *** ERROR: Mooring Lookup grid: Z displacement of -31.0081 is below lower grid limit of -31 for mooring MooringLine_2. Grid must be re-calculated with a lower min Z., and after correcting the lower grid limit again the same error happens for the new grid limit, does anyone have the same experience?

Dear Mina,

Perhaps someone experienced with Bladed will respond, but I suspect it would be better to ask this question to Bladed technical support from DNV.

Dear Jason Jonkman,

I sent an email to them first, but Unfortunately they do not help without renewing the support service.

Best Regards
