- Re: vertical wind profile [1%] by admin, August 25, 2010
- Hi Tim, OpenWind does the same as WindPro and WindFarmer so far as I know. The standard way is to specify the wind speed at hub height only. No account ...
- New Version [1%] by admin, August 25, 2010
- Important update - fixes a bug which can cause small differences to energy capture output.
- Re: Noise input - Total sound power level at source [dB(A)] [1%] by admin, August 11, 2010
- At 10m height? That seems awfully loud. I would choose the 100.2 dB(A) because noise calculations are always worst case. However, you normally would ...
- Re: Multiple Turbine Orientations [1%] by admin, August 07, 2010
- Yes you're right. It will start at the top and work down so you want your catch-all to be last. Glad you figured it out. Nick
- Re: critical failure [1%] by admin, August 04, 2010
- Thanks. Can you send me your workbook please as I run this model on a semi-regular basis and I haven't seen this crash? It should be straight-forward to fix ...
- Re: Multiple Turbine Orientations [1%] by admin, August 04, 2010
- Hi Nathaniel, I enjoyed meeting you too and hope to see you in Oklahoma or Montreal. If you want turbines to jump around between multiple WRGs then I ...
- Re: critical failure [1%] by admin, August 04, 2010
- Hi Dougal, Are you using win7 64bit and the 64 bit executable? If so, how much memory do you have and what is the memory use of openWind before it falls ...
- Re: WRG point file + energy calculation [1%] by admin, August 01, 2010
- HI Jackson, Thanks for sending me the sample turbine files. I used to work in WAsP once upon a time and the procedure I used was that I would define a ...
- Re: Optimizing with respect to Noise Receptors [1%] by admin, August 01, 2010
- Hi Kevin, Yes if you can't get it working, please send me the workbook. Nick
- Re: Bearing of major axis [1%] by admin, August 01, 2010
- Hi Matt, Not all the WRG types have power density information and so this is why I chose to limit the cursor to a frequency rose. Your request is noted ...
- Re: 3D modelling in GE [1%] by admin, July 30, 2010
- Hi again Rajan, I realise I didn't answer your second question about mixed turbines. This is not a problem as the turbine model is associated with a ...
- Re: 3D modelling in GE [1%] by admin, July 30, 2010
- Thanks Rajan, We will be releasing a 3D visualisation module later this year. As for the default models, I have provided several models along with their ...
- Re: Energy Report [1%] by admin, July 29, 2010
- Hi Michael, I am not sure what this is or what it would be used for. Wake losses and TI losses can increase as wind speed increases and so I am not sure ...
- Re: Bearing of major axis [1%] by admin, July 29, 2010
- Thanks Matt, The bearing of the major axis is something you need to input. The 135 value is just put there by me at random as I needed to put something ...
- Re: Ellipses [1%] by admin, July 29, 2010
- Hi Alicia, The switch in the global settings acts as a master switch to turn the capability off and on but it seems to be confusing people so I should ...
- Re: Optimizing with respect to Noise Receptors [1%] by admin, July 23, 2010
- Kevin Kevin Kevin, You don't need to set the layer validity logic for the environmental sensor layers. They do their own special testing. You need to ...
- Re: Ellipses [1%] by admin, July 21, 2010
- Hi Jason,<br /><br />There is now a master switch in the global settings for adjusting to true North. Once enabled, there are switches in WRGs and in ...

- Re: error in optimising the turbines [1%] by admin, July 20, 2010
- Hi Monika, Is the hub height of the WRG the same as the hub height of the turbines you are using? Nick
- Re: WAsP .map Compatibility [1%] by admin, July 19, 2010
- Well I guess we're both embarrassed then. I'll add it to the vector->open in the next release. Thanks Adam. Nick
