Dear Xing Wei,
Prof. Matthew Lackner of the University of Massachusetts developed a custom version of FAST v7 that had some of the features of the TMD submodule of FAST v7. This version was called FAST-SC. (Prof. Lackner and his students also developed the TMD submodule of FAST v8.) More information is the following forum topic: TMDs in ServoDyn module - #4 by Jason.Jonkman.
Best regards,
