Velocity Wind Profile

Velocity Wind Profile

Hi,

May I request that a Velocity Wind Profile be implemented in the next 6 months? This is required for the AEC industry in Singapore. Thank you.

Looks like there is a lot of interest in this one. For those that think this would be helpful, is it specifically velocity you are interested in varying or are there other conditions you need to vary over a surface?

 

Also, if you can comment on the design we have implemented in Project Falcon that would be helpful so that we can better understand what you are looking for. This video shows a wind profile input at 01:50:

The request is for a wind velocity profile that adheres to logarithmic law. For more information in regards to the velocity wind profile, please refer to section C3: Ventilation Simulation Methodology at the following link. http://www.bca.gov.sg/Envsuslegislation/others/GM_Certification_Std2012.pdf Thank you.

According to all international normes, the other key parameter that should change with height, alongwith velocity to build the logarithmic profile, is the turbulence intensity.

Thanks for the additional details. We will reveiw.

Thanks for providing feedback. Please check out the new spatially varying boundary conditions in CFD 2015 and let us know what you think.
