TD_xxx is a toolkit of matlab objects and functions to perform simulation of floating body motions in the time domain. The intent is that the code is extensible, giving the user a high level of control over new forces that impact the motions of one or more floating bodies, tethered or untetethered to one another. All of the linearized wave-hydrodynamics is complete allowing the user to concentrate on adding problem specific behaviors to the system without having to program the relatively complicated wave-body interactions.
Hey. Thanks for this, I found it very useful. In your method of calculating the radiation forces you use a convolution of the acceleration (xddot) with the impulse response function BuoyA5_IR.1 for the single body example. I have attempted to use a convolution of the velocity (xdot) with the impulse response function BuoyA5_KR.1. For some reason, the pitch and surge displacement is incorrect and diverges exponentially. I am wondering have you attempted this? If not, have you any advice on where I might have gone wrong? Thank you
