Aiming at the core problems of slow reading of large-scale result data and weak post-processing visualization caused by the refined finite element analysis of complex aviation structures, a method for fast loading and post-processing visualization of structural analysis result data based on the HDF5 file format was proposed. Firstly, based on the characteristics of the HDF5 file format, a new finite element analysis result data storage format was reconstructed, and the data application class was rewritten using the C++ interface of HDF5 to adapt to the parsing of structural analysis result data. Secondly, combined with the finite element post-processing analysis process, the data index and data reading were optimized, and a parallel loading and fast reading method for finite element result data based on HDF5 files was proposed to improve the reading efficiency of large-scale data. Finally, the program design and software integration were carried out in combination with the SABRE software graphics rendering process. The accuracy and performance tests show that this method has significant advantages in the reading of large-scale structural analysis result data, has higher I/O efficiency than the conventional data processing scheme, and provides a new high-performance data processing solution for efficient and accurate post-processing display and visualization analysis and evaluation of complex aviation structure analysis, greatly improving the user-friendliness of the SABRE system for independent structural analysis software.
