yang7857854 / F2A

F2A is an aero-hydro-servo-elastic tool developed based on AQWA by Yang Yang, a postdoctoral research associate in Liverpool John Moores University for performing fully coupled analysis of floating offshore wind turbines (FOWT). The aero-servo-elastic simulation capabilities are fully implemented within the user_force64.dll which is a built-in DLL of AQWA for external force calculation. For a coupled analysis of a floating offshore wind turbine subjected to wind, wave and current loadings, the aerodynamic loads acting on the rotor, the elastic responses of the blades and tower, and the servo-control are examined through the DLL, considering the influence from the platform motions. The platform position, velocity and acceleration at each degree of freedom are passed into the DLL to update the kinematics of the upper structures. Before being passed into DLL, these terms are transformed from the inertial coordinate system to the local coordinate system of the platform.

Hello Yang, I am trying to run F2A and this error appears can you help me? I am using Ansys 2021 R1.

Hi,

Since F2A will call the dll located in the win64 folder and write a temp file, Thus, I think you need to change the authority permission of the folder. Sometimes the files in sub-folders of Program Files cannot be modified as set by default. You need to enable the authority to write, read, change, remove, etc, for the aqwa/bin/win64 folder.

Kind regards,

Yang

Hello Yang, Thanks for early reply. I am able to run F2A code as mentioned in the user manual. Now, I want to use the .fst file which is generated from OpenFast. It is showing error as shown below, this error may be due to change in version. Can you explain me how to use the file which is generated from OpenFast as I am new to this.

Thanks and Regards echo

Hi,

This error is caused by the wrong format of the .fst file. Please compare TAQWA.fst with the fst file provided in the example folder, and make sure that every variable in your fst file is in the same line with the example.

Hi,

I think you need to modify the input of rhe aqwa result extraction file to make it compatible with your case.

There is another reason to this error. Maybe you are using a later version of AQWA that generates a different structured data file.

Hello Yang, Thank You for quick response. I have another problem, simulation is running fine now, but after extracting the results as defined in the F2A user manual and it is saved in the individual folder. But the obtained .dat files are empty as shown in attached image.

Can you explain why?

Hello Yang, I am trying to rebuild the master code (user_force.f90) using the all source code available in F2A folder in Visual Studio 2019+ intel fortran compiler. user_force64.dll file is generated as usual but by initializing AQWA through cmd shows the following error. It works fine while using dll file provided by you in the F2A folder. image Screenshot 2023-01-02 192304

Please guide me through it. Thank You

Hi,

When you try to run F2A through the cmd window, you need to specify the path of the AQWA input (.dat).

FAST (FAST_IO.f90) has called a subroutine (checkArgs) to identify the input from the CMD window. Please ensure this line is commented out as below.

Kind regards,

Yang

Hello Sir, I already commented out that line in (FAST_IO.f90) in previous trials but it is still showing the same error. c

yang7857854 commented 1 year ago

Hi,

Please try to specify the directory of and filename of the AQWA input (.dat). If this does not help either, then I suspect it is the problem of the OS and I can't suggest more.

Kind regards,

Yang

Hii, The above problem is due to the different versions of the compiler used. May I please know how you build the dll file or which compiler(version) you used?

Thank You

yang7857854 commented 1 year ago

Hi,

The DLL was compiled using VS2013 and Intel fortran 2010.
