I have been trying to produce a Campbell diagram using the scripts from the MATLAB toolbox and I am looking for some advice.
I am looking to reproduce the Campbell diagram from various publications ,  for the IEA15MW. Example from :
My reason for doing this is that I have alternative tower designs that I’d like to replicate the diagrams with. However, my response appears off (particularly with regards to blade modes).
I suspect a combination of my input files ( I did try matching the core settings of the example 5MW which worked fine) and the defined list of linearization points are the cause. I have experimented with using the default linearization points file settings and trying to follow the setup that was described in  using 0-14 rpm in steps of 2 with a fixed 0 pitch angle but none of my approaches have yielded a good result. I have also seen a couple posts here related to MBC3 so I’m not sure if that could also be a potential cause.
Can anyone offer some guidance on how to potentially improve my output? I feel like I am perhaps misunderstanding how these scripts work.
PS: I apologise for the relatively low quality images and I was looking to attach a zip file with some input files but I had some issues attaching those here. I have tested the Campbell script with varying settings (for example: activating different/ all DOFs, varying input files, etc) so not sure how useful including the input files would be.
