Hull Design & Fairing
The design of a vessel in Orca3D begins with the hull model. Hull design is a unique combination of artistic expression and engineering analysis, combining to form a creative process to meet the aesthetic and performance requirements of the vessel.
The software that you use to transform the hull from an idea to a 3D computer model should enrich the creative process, with guidance provided by precise and detailed analyses. With Orca3D, you have complete freedom to create any type of hull, beginning with a concept and carrying through to final fairing, while ensuring that the hull meets your target hydrostatic properties.
Hydrostatics & Stability
The process of hull design is more than simply aesthetics; the hull must meet various other requirements, including overall dimensions, displacement, center of buoyancy, and stability. Therefore, the process of hull design and the analysis of hydrostatics and stability must be closely linked. In Orca3D, the model for these tasks is one and the same; the hull is designed using one or more NURBS surfaces, and these same surfaces are used in the calculation of the hydrostatics and stability properties. In fact, they are so closely linked, that the hydrostatics can be updated in real time, as the hull surface is modified.
Parametric Speed & Power (Level2 only)
Most of the required input parameters are automatically computed from your model, although the user can input or override the values. Results are quickly generated and professionally formatted, and include checks to ensure the validity of the results. Any parameters that are outside of the ranges of the prediction method are flagged.
