WAT - terrain assesment (fitting of plane)

[HPJ]

Hi,

I've been trying to implement the terrain-fitting algorithm in:

"Wind and wake models for IEC 61400-1 site assessment"

(can also be found in the help file of WAT). I am, however, unable to get any sort of reasonable result. I just wanted to doublecheck that the formulas listed in the help-file are accurate?

Thanks

Hi Hans Peter,
It seems like I forgot a factor of 8/(r2^4-r1^4) in the solution. The EWEC 2009 paper was written in a hurry and later I copied the solution to the help file without checking. If you or anybody else would like to see the analytical solution, then send a mail to wengsupport@risoe.dtu.dk and I shall provide a Mathematica Notebook.
Thanks for reporting this. I will correct the help for the coming WAT version 3.1.
Regards,
Morten

Hi Morten,

Thanks for the quick answer!

I definately know the problem of having to hurry :-)

I've sent a request to the weng support email.


Thanks again.
