BMW – Quick Mesh Application

Customer profile

Bayerische Motoren Werke AG, commonly referred to as BMW, was founded in 1916 in Germany as a manufacturer of aircraft engines. Today, the BMW Group, with its 31 production and assembly facilities in 15 countries as well as a global sales network, is the world’s leading manufacturer of premium automobiles and motorcycles, and provider of premium financial and mobility services. The BMW Group sets trends in manufacturing technology and sustainability by being a leader in innovation with intelligent fusion of materials, a technological shift towards digitalization and resource-efficient manufacturing.

Business challenge

The mission of the project was to cut car model development process time through streamlined generation of meshed models from different types of CAD modelers.

Technology solution

• Development of a semi-automatic graphic preprocessor to meet the specifications imposed by the computational fluid dynamics solver used at BMW.

Business value

• Generation of meshes for aerodynamics studies from CATIA V4 and other CAD models
• Shortened development process, from several days to several hours
• Specific application reusing external tools like the Simulog mesh optimization component within the Open CASCADE Application Framework

More about the project

The Quick Mesh Application is now being used by BMW for the preparation of 3D models for analytical studies.

This application was developed following BMW specifications by the OPEN CASCADE specific development team.

Quick Mesh retrieves data from CATIA V4 and other CAD modelers and generates meshes for aerodynamics studies that will meet the constraints imposed by the computational fluid dynamics solver used at BMW.
