How can a wind velocity file be read by the FAST software

Postby Yuqi.Cao » Fri Sep 08, 2017 2:03 am

Dear all,

I am using FAST v8.16 and trying to adopt a InflowFile which contains the wind velocities generated by myself. Then I set the the parameter WindType to be 6 in the input file for In InflowWind v3.01. However, this means the wind velocities will not be read from the file, but be calculated by a user defined function. So, I wonder if there is any method to import a wind velocity file to the FAST software.

Thank you in advance for your kind help

Best regards,

Yuqi CAO

Dear Yuqi,

If you have time series of wind at one point and it is reasonable to assume uniform wind across the rotor (perhaps with shear), then you can use WindType = 2 (uniform wind files) to define your wind. See the InflowWind User's Guide for more information: https://wind.nrel.gov/nwtc/docs/InflowWind_Manual.pdf. If your wind data is more complicated, please clarify.

Dear Jason,
Thank you very much for your kindness. Actually I meant that I wanted to import time series of wind velocities at many points to FAST. For example, the wind velocities of different points in the rotor plane are generated by MATLAB firstly and the response of the turbine is going to be studied using FAST. The wind velocities may be under the condition of typhoon or other load cases. AS a result, the wind velocities need be transfered to FAST. SO, how can these data be imported to FAST? Thank you again for your kindness.
Best regards,

Dear Yuqi,

One way would be to update your MATLAB script so that it can write the wind data in a format that the InflowWind module of FAST can already read e.g. binary TurbSim format. Again, see the InflowWind User's Guide for a detailed description of the formats: https://wind.nrel.gov/nwtc/docs/InflowWind_Manual.pdf.

Dear Jason,
Thank you very much. I will have a try.
