Dear Jason,
I have converted my FAST v8 model into FAST v7 model in order to linearize it with platform DOFs. But the issue I am having that when I enable all 6 platform DOFs then the warring message that appears in FAST v7 simulation is as follows:
I have gone through this post "Large displacement - #2 by Jason.Jonkman and in order to debug the problem I eliminated DOFs as you suggested there.
The simulation runs fine with 2 DOFs, i.e., PtfmSgDOF and PtfmSwDOF. However, when I try to turn on any other platform’s DOF then the above mentioned warning appears.
kindly advise how to solve the problem.
