... between drag components due to differences in solver fidelity. Two different versions of the free surface boundary condition were simulated—the wall condition and the biplane condition. Simulations with the biplane condition yielded consistently higher drag predictions than with the wall condition...

... of the guidelines. When a local model is built and boundary conditions are to be applied, displacement from the global model is often used to transfer the global loads. The difference between a detailed shell local model and the simplified coarse beam/shell global model requires the use of so-called rigid elements...

... scheme, the perturbation free surface boundary conditions are transferred to a representative incident wave surface at each station at each time. The hydrodynamic pressure components are integrated under the intersection surface of the incident wave surface and the exact body position. A strip theory...
