Problems solved by technology

It is difficult to ensure accuracy only through manual operation by engineers
In addition, it takes a lot of time to check before the calculation. If an error is found after the calculation, the calculation needs to be repeated, resulting in waste of resources and even affecting the development progress.

Abstract

The invention provides an automatic simulation analysis method and device based on STAR-CCM +. The method comprises the following steps: starting the STAR-CCM + according to a preset automatic script;reading the grid file to build a simulation analysis model; reading the parameter file to perform parameter setting on the simulation model; performing simulation operation analysis according to thesimulation analysis model after parameter setting is completed; and carrying out post-processing on the operation result to generate a result file. According to the invention, the automation of simulation analysis can be realized, the working efficiency is improved, the cost is reduced, and the accuracy of a simulation result is improved.

Description

technical field [0001] The invention relates to the field of simulation technology, in particular to an automatic simulation analysis method and device based on STAR-CCM+. Background technique [0002] With the rapid development of simulation technology, the accuracy of simulation has been further improved, and simulation analysis has gradually been recognized by development engineers from all walks of life. Compared with real vehicle test verification, simulation analysis has the advantages of short development cycle, reduced test frequency, and reduced R&D costs. It has been widely used in the performance development of vehicle thermal management, aerodynamics, and aerodynamic noise. [0003] The simulation analysis is actually a virtual verification of the test, involving many setting items, mainly including input parameters, physical parameters, boundary conditions, etc. At present, these settings need to be manually completed by simulation engineers one by one, which i...
