Abstract

The invention discloses an automatic finite element calculation method and an automatic finite element calculation system for flowing of fluid in a pipeline, which are capable of remarkably improving the research efficiency of related workers on the flowing problem of the fluid in the pipeline. The technical scheme provided by the invention is that the automatic finite element calculation method comprises the following steps: an upper computer receives an importing operation of a geometric model of the pipeline; the upper computer receives unified setting of parameters for finite element calculation; the upper computer calls a bottom layer finite element calculation model, and automatically divides grids in a standardized manner; the upper computer receives unified setting of boundary conditions; the upper computer calls the bottom layer finite element calculation model, and executes automatic finite element calculation; the upper computer outputs a finite element calculation result.

Description

technical field [0001] The invention relates to a finite element calculation method and system, in particular to an automatic finite element calculation method and system for fluid flow in pipelines. Background technique [0002] The problem of fluid flow in pipelines is a relatively common fluid problem, such as the flow of water in water pipes, the flow of oil in oil pipelines, and the flow of blood in blood vessels. At present, the common way to do research on related issues is to use mature finite element fluid calculation commercial software (such as Ansys, Fluent, etc.) to perform finite element calculations through the GUI interface of the software itself, and analyze and solve problems according to the calculation results. [0003] This conventional approach has certain defects: it requires high operational skills for problem researchers to use finite element calculation commercial software; for pipeline models of different sizes and shapes, it is necessary to repeat...
