Sažetak
Ship structural analysis is usually carried out using commercial FEA software. Besides the many benefits that they bring, there are also limits to the extent a user can alter their functionalities, thus limiting the testing of new ideas in science. In this paper, we present the current state of development and capabilities of open-source software called OOFEM (Object-Oriented Finite Element Method), which has recently been upgraded to enable a linear static analysis of real-world ship structures. We briefly summarise the latest upgrade and demonstrate its workings on a series of test cases including typical ship substructures and structures. We also provide a comparison with NX Nastran, an industry-standard FEA program, and classification societies’ requirements and show that the upgraded version of OOFEM can solve problems that occur in typical linear static analysis of ship structures.
