Aerodyn v15.04 with Parametric Analysis

Postby Mohamed.Fekry » Thu Jan 11, 2018 9:43 am

I am a new user of AerodynV15.04, and FAST v8 also. I need to perform Parametric Analysis to draw Cp(TSR, Pitch angle). Is there any way to do this in Aerodyn v15.04?
Thank you in advance.

Dear Mohamed,

Yes, of course. Using the standalone driver for AeroDyn v15, you can easily run a number of simulations with different uniform wind speeds, fixed rotor speeds, fixed pitch angles, etc. using the Combined-Case Analysis option and use the results to generate a surface of e.g. power coefficient versus tip-speed ratio and pitch angle.

Thank you for your reply.
However, This solution will result in a large number of output files that equals to the number of simulated cases. For example: if I want to perform the simulation for wind speeds ranged from 1 m/s to 16 m/s at 0 pitch angle will result in 16 output files. By the way, this is only at 0 pitch angle and you can Imagine how many output files will be generated if you want to perform the simulation at different pitch angles.
So, I would appreciate if there any other way to obtain the simulation results?

This is a part of my .dvr file (Combined-Case Analysis)

Dear Mohamed,

I agree. You'll then need to write a script to e.g. extract the mean power coefficient (RtAeroCp) over one azimuth rotation, resulting in only one value from each file, from which you can easily plot the surface.
