Problems solved by technology

However, the modeling process of building a 3D model with commercial software is complicated
When the change of the local area of ​​the research object has a significant impact on the overall model, this complete simulation through the multi-physics field coupling of the 3D model will cause the number of grid divisions to be too large, and the computational efficiency of the numerical simulation will be low

Abstract

A method for coupling commercial software and self-programming software mainly comprises the following steps that 1, an analysis model of a research object is established based on a commercial software automatic modeling script and the self-programming software, and coupling transmission parameters and control process parameters are determined; 2, selecting one of the commercial software and the self-programming software, namely the software A, calculating once in advance, outputting a result file, and waiting for the other software, namely the software B, to output a result file; 3, the software B reads the result file of the software A through the coupling interface, the coupling transmission parameters of the software A are mapped to the model nodes of the software B through a data mapping method, the software B calculates once and outputs the result file, and the calculation result of the software B is read and mapped by the software A, and the next calculation is carried out; 4, circularly executing the steps 2 and 3 until the total time step number; by means of the calculation method, coupling calculation and multi-physics field refined simulation between commercial software and self-programming software can be achieved.

Description

technical field [0001] The invention relates to the field of performance analysis of nuclear reactor fuel elements, in particular to a method for coupling commercial software and self-programming software. Background technique [0002] Nuclear reactors are typical multi-physics and multi-scale coupled systems, and the behavior and performance changes of fuel elements are critical to the safety of nuclear reactors. Therefore, it is necessary to use the most detailed and accurate multi-physics and multi-scale coupling model for the behavior and performance analysis of nuclear reactor fuel elements. [0003] The self-programming software developed for constitutive equations can relatively accurately simulate the multi-physics state of the research object, but in order to simplify the calculation amount, a low-dimensional analytical model is usually selected, and a rough representation of the research object in the larger-scale analysis is carried out. Changes in multiphysics c...
