Abstract: This paper analyzes the status of open source finite element solver and commercial finite element solver. Aiming at the problem of large scale numerical computing and analysis in ship design field, a parallel transforming and transplanting mechanism of Calculix based on message passing interface (MPI) is proposed. Combined with high-performance computing capabilities of supercomputer, an efficient and rapid technological solution is found. On the condition of matching the pre and post processing files analyzed by other commercial finite element software, computational analysis uses the method of multi-state and multi-node parallel computation on supercomputer. Hence a ship fatigue strength parallel computation analysis platform is established, and the practical testing examples and results show that the parallel mechanism greatly reduces the computation time.
