Dear Jason,
Since the Seismic Loading module is not yet available in FAST v8, I was thinking about at least implementing something similar yet simpler functions in v8. From what you suggested in topic: [url]Foundation Stiffness and damping in FAST v8] and the applied force model in the documentation of the Seismic Loading module, do you think I could utilise AddCLin and AddBLin and modify the fowllowing equation in HydroDyn.f90:
m%F_PtfmAdd = p%AddF0 - matmul(p%AddCLin, q) - matmul(p%AddBLin, qdot) - matmul(p%AddBQuad, qdotsq)to something like
m%F_PtfmAdd = p%AddF0 - matmul(p%AddCLin, q - qDesired) - matmul(p%AddBLin, qdot - qdotDesired) - matmul(p%AddBQuad, qdotsq)where qDesired and qdotDesired represent the sinusoidal equations of the desired displacement and velocity?
Thank you very much!
Best regards,
Yuanchuan Liu
