Opportunities of using open-source FEA software in ship structural design

The paper deals with characteristics and design of FEA software for ship structural analysis. Technological changes that occur in naval architecture and related disciplines that influence its relative performance are identified. The place of such tool within ship structural design is analysed and important requirements are formulated. Opportunities of use of open-source software are discussed. Importance of object-oriented programming for its code architecture is demonstrated. FEA software called OOFEM is selected to demonstrate the relevance of the aforementioned reasoning. At the end, classification societies’ rules regarding finite element analysis of ship structures are analysed and used to assess OOFEM capabilities.
