Problems solved by technology

If they are all integrated into the platform, it will inevitably bring about confusion in software engineering management
Moreover, the input and output file analysis of commercial solvers is generally not open source, and it is difficult to find ready-made solutions from the Internet.

Embodiment 1

[0058] Embodiment 1. A CAE file conversion method based on a general read-write framework.

[0059] see figure 1 , the CAE file conversion method based on the universal read-write framework provided in this embodiment includes:

[0060] S1. Read the file content of the model file A in line order.

[0061] Specifically, in the process of CAE data processing, there will be various model files in different formats. These files can be mainly divided into two categories: external files and internal files. Among them, external files mainly include CAD files and CAE grids. Files and solver input and output files; internal files mainly include X3D files, VTK files and solver parameter setting files, and internal files can usually be divided into two categories: the first category is model display files, including X3D files (CAD files and The web display file of the CAE grid file) and the VTK file (post-processing result display file); the second type is the solver parameter setting ...

Embodiment 2

[0091] Embodiment 2, a CAE file conversion device based on a universal read-write framework.

[0092] see Figure 5 , the CAE file conversion device based on the general read-write framework provided in this embodiment is used for conversion between various model files in the CAE data processing process, including a reading module 21, an analysis module 22 and a mapping conversion module 23.

[0093] Wherein, the reading module 21 is mainly used to read the file content of the model file A in line order;

[0094] The parsing module 22 is configured to parse and map each line of file content in the model file A to the unified data model 22 according to the format of the model file A according to the pre-configured read configuration file.

[0095] The mapping conversion module 23 is mainly used to map the unified data model 22 into the model file B according to the format of the model file B according to the pre-configured writing configuration file.

[0096] Wherein, the rea...

Abstract

The invention discloses a CAE file conversion method and device based on a general reading-writing framework. The conversion method comprises: S1, reading the file content in the model file A according to the row order; S2, mapping the file content of each row in line with the format analysis of the model file A according to the pre-configured reading configuration file in the general reading-writing framework; S3, according to the pre-configured writing configuration file in the general read-write framework, mapping the unified data model to the model file B in the format of the model file B. The general reading-writing framework and the intermediate bridge unified data model are introduced in the invention, the reading configuration file and the writing configuration file are written in the general reading-writing framework, and the unified data model is combined to convert the model file A generated in the CAE data processing process into the model file B of different formats, to realize mutual conversion of model files of different formats.

Description

technical field [0001] The invention relates to the field of CAE model file conversion, in particular to a CAE file conversion method and device based on a universal read-write framework. Background technique [0002] Commercial CAE software basically comes with professional pre-processing software and post-processing software, most of which support the input of mainstream commercial CAE models. Of course, the mutual conversion between models is also indirectly realized, for example: ABAQUS and NASTRAN support mutual conversion. [0003] Here I want to mention HyperWorks, which has a special pre-processing software HyperMesh. The specialty of HyperMesh lies in the function of grid division. At the same time, HyperMesh supports many different solver input and output formats, so that after using Hypermesh to divide the finite element grid of the model, the calculation model can be directly converted into different solver file formats, so that the corresponding solver can be ...
