Analysis on Wave Generation and Hull:
Modification for Fishing Vessels

Abstract This paper analyses the fishing vessel design in terms of wave generation and hull modification. The objective is to distinguish the fishing vessel designs
between an existing hull and a modified one. This is then used for simulation via a
CFD software to determine the better layout. The design is created in the Autodesk
Inventor software based on the vessel particulars from the designated design. These
designs are then transferred to the Flow3D software for the result. The configuration
is done via a multi-block feature. Based on the literature, the deep V hull is proven
to be more advantageous in rough conditions as it is more efficiently operational at
a preferred velocity as opposed to the round bottom hull. The successful simulation
outcome of this study is influenced by the different total number of mesh elements.
The distinct sum of mesh elements impact on precision of the outcome, simulation outcome, mesh execution and resolution is achieved. Several suggestions are
recommended on ways to run a CFD simulation successfully.

9.1 Introduction
Primary and secondary waves surrounding a vessel characterise the wave system by a
shifting vessel sailing on an unrestricted or restricted body of water. The central wave
system constitutes the front wave, a lateral depression of water and a stern transverse
