quality matrix

[3sdb]

Dear everyone:
Now I use Openfast's linearization to calculate the mass matrix and stiffness matrix of the 5mw wind turbine. After checking mbc, I learned that the names of the results I need to find are MBC-M and MBC-K. After checking GetMats, I found that the mass matrix and stiffness matrix will be output only when MdlOrder=2. The MdlOrder in the line file I output is 1. I would like to ask how to adjust MdlOrder to 2

Dear @3sdb,

I'm not sure I understand your question. It looks like you tried to upload a PNG picture, but the link is not correct. Perhaps you are you using the old GetMats.m script in MBC that was compatible with FAST v7 rather than the new fx_getMats.m script that is compatible with OpenFAST?

Best regards,
