Abstract

The invention discloses an open source finite element solution and optimized analysis method. The method comprises the steps of simplifying and abstracting an entity needing to be optimized and generating a first code of the simplified entity; establishing an open source finite element total environment, providing boundary conditions, and implementing modeling of the first code and generating a universal INP text file; extracting parameters in the INP text file by detecting text file partitions, and converting the INP text file into a standard generating solver input file with variable parameters; calculating node stress and displacement, and writing results into a result file; comparing parameters in the result file and expected optimized parameters, judging whether optimization conditions are met, and writing out and displaying the result file if the optimization conditions are met; and if the optimization conditions are not met, modifying INP text file parameters and performing loop iteration, until the optimization conditions are met. The open source finite element solution and optimized analysis method has the advantages that the dependency of enterprises on traditional commercial CAE and FEA software is reduced, and the product design and optimization cost is reduced.

Description

technical field [0001] The invention belongs to the field of mechanical design, and relates to an open-source finite element solution and optimization analysis method. Background technique [0002] The finite element method is the most widely used numerical analysis method in the structural analysis of mechanical systems, and plays an important role in large-scale scientific calculations in the fields of national defense and economic construction. With the continuous development of commercial finite element software, the functions are gradually becoming more perfect. The finite element calculation provides strong support for complex numerical analysis, improves the calculation speed and work efficiency, and promotes the application of finite element in large-scale structural engineering. [0003] In modern finite element analysis, the scale of the problem is often very large, and its structure is very complex. Traditional computers are limited by CPU calculation speed and st...
