shapes.
2.The desingularization method shows no difficulty in treating the body-free surface intersection point.
3.For the desingularization method, no special treatment for the coefficient of the influence matrix is
necessary. The stability of the desingularization method is better than that of the conventional
boundary integral equation method.
4.The desingularization method is promising for further application to floating structures with arbitrary
shape undergoing arbitrary motion.
