Computational Fluid Dynamics in the Ship Design Process; CALYPSO

The CALYPSO project - Computational Fluid Dynamics in the Ship Design Process - was launched in order to integrate the use of CFD (Computational Fluid Dynamics) in the interactive hull form design process at European shipyards. Before CALYPSO, use of CFD usually took place in separate processes carried out by highly skilled specialists, while CALYPSO's main goal has been to enable ship designers to exploit CFD as an integral part of the hull form design process. The objective be-hind this goal was partly to shorten the development cycle, partly to improve the quality of the ship designs, and finally to enable a multi-perspective design process.

Being a technology transfer project, it has been the mission of CALYPSO to identify and push the limits of applicability of CFD at shipyards as much as possible.

A main result of this effort has been the establishment of a CFD validation cookbook in which the experience of applying CFD to a number of carefully planned cases has been documented in a structured way. A part of this cookbook will be made publicly available.

A number of developments in leading edge CFD codes have been made, addressing the issues of robustness and applicability. This has improved the quality of predictions and extended the range of ships, for which CFD calculations can be made. These developments are or will be made commercially available in the codes in question.

A design methodology has been developed, providing valuable guidance in the hull form design process as well as providing new hull form variation capabilities, which will be made commercially available.

A Designer's Workbench has been developed, enabling applications on heterogeneous platforms to be integrated in a plug-and-play fashion. The workflow is based on use cases specified by experienced ship designers. Product model data exchange is based on ISO 10.303 STEP AP216 interfaces. Components of the workbench and interfaces will be made commercially available.

At the time of completion of the CALYPSO project in the summer of 1999, the experience in using the integrated set of CALYPSO tools is still rather limited. Quantified measurements of benefits are therefore not yet available. But it is the firm belief of the CALYPSO consortium that the results of the project have contributed substantially towards a multi-disciplinary hull form modelling process, enabling considerable cost and time savings in the overall manufacturing and operation of ships.
