heal.abstract	Computational Fluid Dynamics (CFD) simulations are essential in modern ship design, allowing for the prediction and analysis of fluid flow around hulls and propellers by solving the Navier-Stokes equations. This technology enables engineers to assess hydrodynamic factors such as resistance, propulsion, and wave behavior without extensive physical testing, optimizing hull forms and improving efficiency while reducing fuel consumption and emissions. The Tokyo 2015 Workshop on CFD in Ship Hydrodynamics provided a platform for researchers and industry experts to showcase advancements in CFD methodologies, featuring benchmark test cases that allowed participants to compare their results in resistance, propulsion, and wave interactions against experimental data. Insights from this collaborative effort are vital for enhancing CFD accuracy and reliability, driving the design of more efficient and sustainable ships. The primary aim of this master's thesis is to compute various flow characteristics of the Japan Bulk Carrier (JBC) model operating under different conditions in calm water using the CFD software Star CCM+. The results will then be compared with relevant metrics obtained from towing experiments. This master's thesis is divided into four sections. It begins with a brief introduction to ship resistance, followed by an overview of the CFD theoretical background and methods that establish the fundamental principles of the study. This includes the conservation equations, their discretization and solution, turbulence modeling, wall treatment techniques, and free surface modeling. The thesis then presents the case study, detailing the geometry, mesh creation, and physical problem setup (pre-processing phase). It concludes with the simulation execution, result retrieval (post-processing phase), and a comparison of these results with relevant data obtained from experimental fluid dynamics (EFD) studies.	en
