Problems solved by technology

[0003] Common simulation software currently on the market include Nastran, Ansys, etc. The main functions of these simulation software include the analysis and display of data and the storage and retrieval of models, programs, data, and graphics. However, the common data interaction in these simulation software Files, when simulating large-scale models, due to the large size of the transferred files, files with a size exceeding 1GB are very common, so in the process of transmission and reading and writing, it will cause efficiency and correctness stuck points, affecting the efficiency of simulation calculations and stability

Abstract

The invention discloses a data compression method for a simulation file, electronic equipment, and a storage medium. The compression method includes the following steps: obtaining data supported by the simulation file, classifying the data type according to the data content, and establishing a mapping relationship; identifying the data to be compressed The data type of the data, and match the preset compression method for the data to be compressed according to the mapping relationship. According to the characteristics of the simulation file, the present invention adopts different compression strategies for different types of simulation file data, which can reduce the file size without affecting the organizational structure of the file, so that the compression of the simulation file can be compatible with parallel reading and writing and partial reading write features.

Description

technical field [0001] The invention relates to the technical field of data compression, in particular to a data compression method for simulation files. Background technique [0002] Simulation software refers to computer software specially used for simulation. Simulation software has been developed since the mid-1950s. Up to now, there have been simulation software systems with database as the core, simulation software systems using artificial intelligence technology, and virtual reality simulation platforms. Its development complements the development of technologies such as simulation applications, algorithms, computers, and modeling, making the simulation software more powerful and flexible, and can be oriented to a wider range of users. [0003] Common simulation software currently on the market include Nastran, Ansys, etc. The main functions of these simulation software include the analysis and display of data and the storage and retrieval of models, programs, data, a...
