Description

technical field [0001] The present invention relates to the technical field of digital simulation models, more specifically, to a correction method and system for digital simulation models. Background technique [0002] With the development of computer simulation technology, digital simulation has become an important means for human beings to understand the physical world and explore and change the physical world. The key technology of digital simulation is to build a digital simulation model that can accurately describe the simulated object. The so-called digital simulation model refers to the mathematical description of some essential properties of the research object related to the research purpose. In order to be able to solve and calculate these digital simulation models on a computer, the digital simulation models need to be represented by some kind of modeling tool. [0003] At present, the commonly used modeling tools include general modeling tools and professional...

Problems solved by technology

[0004] The traditional digital simulation model modeling and verification process are two relatively independent processes. That is to say, after the digital simulation model is established, the verification result of the model only gives a quantitative index to measure the accuracy of the model. If the quantitative index is low ( Indicating that the accuracy of the digital simulation model is not high), the modeler needs to correct the digital simulation model by himself, and then repeat the model verification process until the digital simulation model meets the expected index requirements, so repeated, resulting in the correction efficiency of the digital simulation model lower
