TWO-DIMENSIONAL CALCULATIONS OF THE MOTION OF FLOATING BODIES

Attention is focused on the feasibility, the advantages, and the limitations of using numerical simulation techniques in the study of floating-body motions. Two simulation techniques, the Generalized Arbitrary Lagrangian-Eulerian (GALE) method and the Transient Potential Flow (TPF) method, have been considered. To assess their accuracy and practicality, both methods have been used to calculate the heaving of a semi-submerged circular cylinder in the free surface. (Modified author abstract)
