Re: Pitching subroutine fortran question

Thanks for your reply Bonnie, I have just run my simulation again and it now works! I commented it out weeks ago because I kept getting an error from FAST saying that it couldn't find Pitch.ipt even though it was in the same directory as the .fst file as you quite rightly state. Now it works and I h...

Pitching subroutine fortran question

Hello. here is a snippet I have taken from my pitching subroutine written into the framework of 'PitchCntrl_ACH.f90'. I have had problems getting the 'PitchFileName' variable to read in the name and file location of the pitch input file which contains the variables for the subroutine. As you can see...

Re: Unusual furl behavior happening.

I have been trying to make this event happen and I believe that I have got close to the cause. Looking at the plots I have attached, you can see the difference int he wind input file. In plot 1 the last ramp down in the wind is slow, from 5.5 m/s to 3.5 m/s over 170 seconds. In plot 2 the last ramp ...

Unusual furl behavior happening.

Hello all, I have a furling and pitching model of what is effectively a burgey type turbine. I have managed to test the model in a variety of states and using real 1 second wind data from site with very good correlation with one exception. When the wind speed drops below the pitching wind speed, aft...

Re: Total beginners advice needed - Pitch control routine

Hello all, after much head scratching I am posting my question. I am using a modified version of 'PitchCntrl_ACH' for my passive pitching routine. I have re-compiled fast using the make file for mingw and, when I run FAST, I get the following error: - ------------------------------------------------...

Re: Compiling FAST V7 using MinGW in Windows with make file

Bonnie, I this has solved it. I was half right. I had $(Inter_Dir) in lower case instead of $(INTER_DIR) . I hadn't spotted this until now, and I also didn't realise that this was case sensitive. I have just re-run the compiler and now get the following: - -------------------------------------------...

Re: Compiling FAST V7 using MinGW in Windows with make file

Bonnie, thank you for your response. The forward slash solved the first problem thank you. I had been using back slashes. I know get a compile error which forces the compile to abort. --------------------------------------------------------------------------------------------------------------------...

Re: Compiling FAST V7 using MinGW in Windows with make file

Ok, I think I have solved the 'sharedinflowdefs.obj' error because I have downloaded the 'InflowWind Archive for Windows® (EXE 818 KB) (v1.02.00c-bjj, 818 KB, 9-August-2013)' from the NREL website. However now when I run mingw this is what happens: - Command line input ******************************...

Bonnie, thanks for your help. I have updated the archive files to the ones required for compiling. This took me forward a little bit however I get stuck again.

Re: Pitch axis - Not on chord line!

Hi Bonnie, thanks for your response. Just to clarify, the blades I am modelling are straight along their span wise and edge wise directions but the pitch axis is offset from the chord line in the global x direction, downwind. In the image below should clarify what I mean. The pitch axis is located a...

Pitch axis - Not on chord line!

Hello, The rotor I am modelling has the pitch axis totally separate from the chord line. It is offset so that the pitch axis is located at approximately 30% of the chord length from the leading edge, and is offset downwind by 70 mm. No part of the pitch axis goes through blade. This is to say that a...

Thanks for the prompt response Jason,
I'll read through again the IVF compile document and see how I get on.
