Dear Dr. jason,
I want to simulate the coupled dynamics of IEA-15MW when a blade suddently break down at a specified spanwise position (say 0.5R) using FAST.
I find this kind of simulations are rarely reported in wind energy communities, and I am trying to use FAST for such simulations with some code customizations.
Now, I have two plans for blade breakup simulation using FAST:
(1) Simplyly set the aerodynamic forces and gravity force to zeros for a certain range of blade span, say 0.5R-1.0R.
(2) Reconstruct the AeroDyn mesh and BeamDyn mesh (or ElastoDyn? ) when the breakup occures.
Could you give me some advice and briefly comment on my two plans whether they correctly representing the real blade breakdown event?
Best regards,
Lin Yang.
