Linear Resist. Coef. [m/s]:
Roll Lin. Damp. Coef.[kgm2/s]:
Assumptions:
- A barge like vessel is floating on the still water surface, the motion, induced wave and added mass effect is neglected
- It's calculated a time series of linear roll and heave, with three degress of freedom (x, y and rad)
- Model is considered stable (GM > 0), and Roll ressonates when GM < 0
- Block Coefficient is used in calculations, but not plotted in the transversal and longitudinal animations
