Three-dimensional model generation method and device based on physical mechanism numerical simulation

The invention belongs to the technical field of three-dimensional modeling processing, and provides a three-dimensional model generation method and device based on physical mechanism numerical simulation, and the method comprises the steps: extracting description features of model description contents, the model description contents represent demand information for a target model, and the model description contents comprise characters and/or graphs; subject information and/or individual information of the model are/is determined according to the description features, the subject information represents the overall structure of the target model, and the individual information represents the individual features of the target model; and performing three-dimensional construction according to the main body information and/or the individual information, and generating the three-dimensional model corresponding to the model description content, so that the method can adapt to generation of the three-dimensional model
