Embodiment Construction

[0016] The parametric simulation method of the fluid flow problem of the mechanism of the present invention uses LabVIEW to control the execution sequence of Gambit and Fluent according to the data flow, so as to realize the parametric modeling and simulation of the mechanism, such as figure 1 As shown, the method includes the following steps:

[0017] Step 1: Input the structure size parameters, fluid physical parameters and working condition parameters that need to be modified in LabVIEW;

[0018] Step 2: Utilize LabVIEW to edit the Gambit log file, modify the relevant mechanism structure size parameters in the Gambit log file according to the content input in step 1;

[0019] Step 3: Use LabVIEW to run the Gambit start command statement, start Gambit, and call the Gambit log file modified in step 2 as the initialization file to initialize, automatically complete the establishment of the mechanism model and the division of the grid, and generate a model that matches the stru...

Abstract

The invention relates to a parameterization simulation method for a flowing problem of mechanism fluid. According to the method, a sequence for executing Gambit and Fluent is controlled by using LabVIEW according to a data stream, structural sizes, fluid properties and working condition parameters of relevant mechanisms in a Gambit log file and a Fluent log file are edited and modified by using the LabVIEW, and the corresponding log files are executed by starting Gambit software and Fluent software by using LabVIEW, so that Gambit modeling parameterization and Fluent simulation process parameterization are realized. The method is favorable for parameterization of a simulation process for the flowing problem of the mechanical fluid, and the simulation calculation efficiency is improved.

Description

technical field [0001] The invention relates to a parametric simulation method for the fluid flow problem of a mechanism. Background technique [0002] Modern computer technology has been widely used to solve engineering practical problems. Gambit and Fluent software are matched, and are widely used in the simulation analysis of fluid flow problems in institutions. The simulation of fluid flow problems in traditional mechanisms must be performed in the order of geometric modeling, meshing, and iterative calculations imported into Fluent software. However, geometric modeling, meshing, and other operations require a lot of work and take a lot of time and energy, the simulation efficiency is low. [0003] Fluent and Gambit software have the function of recording operation steps, and the operation steps can be stored in log files. By replaying the log file, the simulation process can be repeated to obtain the simulation result. The continuous upgrade of LabVIEW software make...
