Hello everybody,
I am new to this forum, and I would first like to thank you for providing and supporting your wind turbine analysis tools!
I am currently trying to build a model using flexible bodies / mnf files for the blades, which I create using ANSYS. I took your 5MW model, removed all blade-specific lines from the .adm file, and rebuilt the blades with mnf files in Adams/View.
One thing I found from the ADAMS MD R3 help (should be 2008r1) is, that only the C++ Solver of Adams can handle multiple GFORCEs on one flexible body correctly. Using the Fortran Solver always orients all GFORCEs that lie on a common flex-body in parallel direction.
Using the Fortran Solver and my MNF-model, I can run simulations, but they are incorrect, due to the mentioned limitations. However, when I try to run the MNF-model with the C++ Solver and the Aerodyn-Subroutine, I get the following error:
[code]---- START: ERROR ----
GFOSUB(11001, 1, 1, 0, 11001) has been illegally defined. A new functional dependency on the measure
TDISP(11001,1,1) has been encountered during execution.
---- END: ERROR ----
Error calling INFARY for blade element coordinates.
Aborting A2AD.[/code]
in this thread: click me in the third to last and second to last post I could read, that someone else had the same problem, and that it is caused by some calls of the undocumented INFARY instead of SYSARY, that trouble the C++ Solver, but not the Fortran Solver.
So here are my questions:
- Is it basically possible to use Aerodyn v13.00.00a-bjj with A2AD and the C++ version of the ADAMS solver?
- Do you have any experience or recommendations for modeling the blades using MNF files / flexible bodies instead of the current way of modeling?
Thank you very much,
