Dear Jonkman,
I want to linearize NREL 5MW_ITIBarge_DLL_WTurb_WavesIrr as Mohamed in Fri Jun 26, 2020 7:57 pm. But I met some problems and the above discussion may not solve my problem. I enabled only two DOFs, GenDOF and PtfmPDOF. But when I run linearization, but it aborted.
Could you please help me?
