Abstract
The FORTRAN routine AMADIFF (Added Mass and Damping; Irregular-Frequency-Free), which calculates added mass and damping of two-dimensional cylinders floating in the free surface of deep water by the integral equation method using the exact Green's function is described. The extended boundary condition method, or the lid method, in which source is distributed along the waterline inside the cylinder as well as on the wetted surface of the cylinder, is used to suppress irregular frequencies
