COMPARISON OF HIGHER-ORDER BOUNDARY ELEMENT AND CONSTANT PANEL METHODS FOR HYDRODYNAMIC LOADINGS

This paper presents the description of a higher-order boundary element method (HOBEM) for calculating linear hydrodynamic loadings on large floating bodies and comparison with constant panel methods and HOBEMs that are employed in conjunction with the hybrid boundary integral equation procedure, for a variety of structural configurations. It was concluded from the study that HOBEM has several important features: it uses many fewer boundary elements and much less computer time, with higher accuracy than conventional methods. In addition to these, the computer code for hydrodynamic loadings can easily be used for finite element structural analysis.
