Automatic data conversion method between three-dimensional modeling software and finite element analysis software

The invention discloses an automatic data conversion method between a three-dimensional modeling software and a finite element analysis software, which comprises the following steps of starting the finite element analysis software, loading the model and performing finite element analysis; starting the three-dimensional modeling software in the finite element analysis software; reading files and performing finite element analysis in the finite element analysis software; saving the result in format of data file by utilizing a data post-processing module and the read and write function of the finite element analysis software; and circularly running the above processes by utilizing the process control command of the finite element analysis software. The automatic data conversion method achieves seamless integration of the powerful modeling function of the three-dimensional modeling software and the finite element function of the finite element analysis software and provides a scientific, high-efficiency and reliable solution for design and analysis of a complicated mechanical system, thereby increasing the product design accuracy and design efficiency.
