Webinar: Toyota Drastically Reduces Simulation Time with Automatic CFD Pre-Processing Workflow
Toyota Cuts CFD Pre-Processing Time by 91% with Fidelity Autoseal and Automesh
Streamlining CFD for Automotive Applications
Creating a detailed CFD model for vehicle aerodynamics or HVAC studies has traditionally required a huge amount of manual work. Engineers often spend days or weeks on CAD cleanup and mesh preparation before simulations can even begin.
Toyota recently demonstrated how this bottleneck can be eliminated. By developing an innovative CFD pre-processing workflow, they reduced their total pre-processing and meshing time by 91%. In this on-demand webinar, Toyota engineers share how they achieved this breakthrough.
The Challenge: Complex CAD Models in Automotive CFD
Accurately predicting external aerodynamics, underhood flows, and heating, ventilation, and air conditioning (HVAC) performance requires simulation domains with thousands of components in CAD format.
The primary difficulty is preparing these complex models for CFD analysis with a finite-volume solver. Traditionally, engineers must:
-
Close gaps between surfaces
-
Eliminate irrelevant geometry not in contact with the fluid
-
Resolve interferences before generating surface and volume meshes
Each of these steps typically requires manual intervention using pre-processing tools—slowing projects, consuming valuable engineering resources, and increasing the risk of error.
The Solution: Automated Pre-Processing with Fidelity
Toyota developed a streamlined workflow by combining two advanced technologies from Cadence Fidelity™:
-
Fidelity Autoseal – Automatically closes gaps in CAD geometry, removing the need for manual repairs.
-
Fidelity Automesh – Generates robust volume-to-surface meshes directly, eliminating the tedious manual meshing process.
By integrating these tools, Toyota achieved faster, more reliable CFD model preparation, making it possible to explore more design variations within the same timeframe.
