Problems solved by technology

[0004] Simulation technology has been integrated into the performance analysis and simulation process of complex products in multiple disciplines. The simulation platform and the number of simulations continue to increase, and more and more simulation data are generated. However, it is still difficult for the design department to efficiently obtain and use simulation data to support products. The reasons for the design optimization are as follows: (1) The historical simulation data has a certain guiding significance for the current product simulation, but the simulation data is large in number and scattered and independent, lacking effective organization and management, and it is diff

Embodiment Construction

[0052] The method for unified integration and visualization of heterogeneous simulation data of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0053] First, extract all the historical simulation model information, construct the simulation model descriptor and store it in the database, and establish the mapping between the simulation model and the simulation model descriptor.

[0054] Before performing simulation analysis on a new design model, first construct the simulation model descriptor corresponding to the model, and then use the similarity evaluation method based on the simulation model descriptor to retrieve similar simulation cases to guide the current product simulation.

[0055] Then, an optimal generation method of the intermediate grid model based on GA is proposed, and the final intermediate grid model is quickly generated by using the optimal acceleration method based on the hybrid grid density field contro...

Abstract

The invention discloses a heterogeneous simulation data unified integrated visual method. The method includes the steps that firstly, a simulation model descriptor library is built, and a similar simulation case is retrieved; secondly, according to the simulation cases retrieved in the first step, simulation analysis of a to-be-simulated model is guided to obtain a multi-domain heterogeneous simulation model, and a middle grid model optimization generation method based on GA is adopted to build a middle grid model; thirdly, according to topological information and a space position relation of the middle grid model and the multi-domain heterogeneous simulation model, mapping interpolation association between the middle grid model and the multi-domain heterogeneous simulation model is constructed, and multi-domain simulation results are represented on the middle grid model in a unified and integrated mode; fourthly, middle simulation results are transmitted to a design platform to display multi-domain heterogeneous simulation data. Unified and integrated fidelity visualization of the multi-domain heterogeneous simulation data in the design environment can be achieved, and design staff can quickly obtain and use accurate simulation results for design deciding, so that design cost is reduced, and design efficiency is improved.

Description

technical field [0001] The present invention relates to the fields of CAD (Computer Aided Design, computer-aided design) and CAE (Computer Aided Engineering, computer-aided engineering), in particular to a unified integrated visualization method for multi-domain heterogeneous simulation data based on an intermediate model. Background technique [0002] In the process of modern product development, simulation has become the third verification method of product design after theory and experiment. The development and improvement of traditional products requires physical experiments to verify the design methods and tools to ensure product performance. It requires a large amount of investment in personnel, equipment, and funds. The product development cycle is long and the cost of research and development is high. It has been unable to meet the increasingly competitive market. Demand, while CAE-based simulation technology can reduce or even completely replace traditional physical...
