Toyota Drastically Reduces Simulation Time with Automatic CFD Pre-Processing Workflow

Creating a detailed CFD model for automotive applications normally requires a huge amount of manual work. Toyota reduced its total pre-processing and meshing time by 91% thanks to an innovative CFD pre-processing workflow and, in this webinar, they will show you how.

Accurately predicting external aerodynamics, heating, ventilation, and air conditioning of vehicles requires setting up simulation domains with a high number of components in CAD format. The main difficulty in working with so many components is creating the watertight surface needed to perform proper CFD analysis with a finite-volume solver. This involves:

• Closing gaps
• Eliminating surfaces that are not in contact with the fluid
• Resolving interference issues before generating a surface and volume mesh

These tasks are usually done manually with pre-processing software that includes CAD handling and mesh-generation capabilities, requiring significant work and time.

Toyota developed a pre-processing workflow that integrates the advanced gap-closing capabilities of Cadence Fidelity Autoseal and Fidelity Automesh volume-to-surface meshing to eliminate this manual process.
