After reading some posts and a quick scan of the user guide, my understanding of the FAST/OpengFast linearization capability is that, at the current stage, only FAST V7 is able to do a 2nd order Linearization (e.g. output MCK matrix). Whether the above is correct or have I missed something? It would be apricated if you can help to clarify this. If the above statement is correct, is there any plan of implementing the 2nd order linearization into a future OpenFast version?
The 2nd order linearization is pretty handy to calculate a floating platform mass matrix when only system and wind turbine information is known. What I am currently doing is getting the MCK matrix from the FASTV7, apply the result to OpenFast afterwards. It would be nice if OpenFast itself can preform the 2nd order linearization.
