Virtual Blade Model (VBM) for wind turbine.
 
Hi everybody,

I had a question about doing a simulation with help of VBM on a 2-bladed
horizontal axis turbine.

The mesh that I am working is a horizontal axis turbine in compare with the
tutorial example, that I had from FLUENT company, in which it
has a vertical axis rotor of a helicopter in its mesh.

My problem is at the very last step of defining the case in FLUENT. When I
put all my information in the "Rotor Inputs" panel, after clicking on
change/creat to save the changes, by clicking on OK button I will get the
fallowing error:

================================================== ===================
1000000 ERROR: Cell ID not determined 1000000 allocate_memory
/usr/local/Fluent.Inc/fluent6.3.26/Inamd64/3d/fluent.6.3.26[0xdd6fcb]
/usr/local/Fluent.Inc/fluent6.3.26/Inamd64/3d/fluent.6.3.26[0xdd6f21]
/lib64/libpthread.so.0[0x3de400e4c0]
libudf/inam64/3d/libudf.so(allocate_memory+0x6a9)[0x2ad5ac63ef5b]

Error: fluent.6.3.26 received a fatal signal (SEGMENTATION VIOLATION) Error
Object: #f
================================================== ===================

I am pretty sure that my settings have no problem, as long as I am able to
run the simulation for the tutorial example. My idea is that I am doing
something wrong, or should have something in my mesh. Because based on the above error, FLUENT can not recognize my rotor zone.


Thank you for your time and consideration and I am looking forward for your helps and answers.

With regards

Hey,

The tutorial is not available on the web. We got it from FLUENT. You should contact them directly and request for the tutorials and the UDF's for the VBM (Note that the files are big and can't be sent via Email and you will receive it on a CD from FLUENT).

Provide me an Email address and I can send you the tutorial PDF, so that in mean while you can read about it.

I hope that this was helpful.

Good luck with you design! ;)

Dear all,

After posting this post I received lot of CMs about sending the tutorials and files for VBM, but unfortunately I won't be able to do this for every single of you and I gave it up after sending it to very two requests. I advised you guys to contact FLUENT under aca-support@fluent.com and request the tutorials and related files from them. It is part of their customer service and support to respond you and send the required files to you. Please don't send me your Email to get those files.

I wish all of you best of luck with your projects and research.

With regards

Hey,

VBM UDF can be provided via the company that provides you FLUENT licences. Simply ask them and tell them the version of FLUENT that you are working with and they will send everything for you.

Best,

Teymour
