Current state of development of OOFEM, an open- source tool for FEA of ship structures
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.
