Abstract

The invention discloses a distributed parallel grid generation software framework. The framework comprises: a client module which has a visual data management function and is provided with a graphic human-computer interaction interface, a message intermediate module which is used for executing asynchronous message transceiving operation and visualized data serialization operation, and a server module which runs on a computing cluster in a parallel mode, supports distributed grid data management and executes a grid parallel generation function. According to the invention, the huge requirement of large-scale CFD application for the grid is met, and a user can access the grid generation service anytime and anywhere. The framework has a friendly graphical user interface (GUI) with which a usercan interact and drive the provided functions.

Description

technical field [0001] The invention belongs to the grid generation field of computational fluid dynamics (abbreviated as CFD), and specifically relates to a distributed parallel grid generation software framework based on a C / S architecture. Background technique [0002] Mesh generation is the preprocessing step of CFD analysis, and the size and quality of the generated mesh will have a significant impact on the CFD simulation results. With the continuous development of high-fidelity CFD simulation, the corresponding mesh size has increased greatly. In industrial CFD applications, the grid size of the simulation application for the Reynolds average NS equation has reached 1 billion, and the grid size in the full-resolution large eddy simulation has even reached 10 billion; in addition, with hundreds of billions of grid points The computing grid has been used in basic research. It can be seen from this that large-scale CFD applications require larger and larger computation...
