4 Methods for Muffler Modeling

A Brief Overview of Exhaust Simulation A proper model of your exhaust system provides a critical boundary condition for your underhood/underbody thermal management. Many different simulation methods are chosen today based on the level of fidelity that is required and the boundary conditions that are available. There are four widely recognized methods for simulating exhaust systems....

The Importance of Transient Simulation for Underhood & Underbody Packaging

Packaging constrictions in new vehicles dominate the positioning and organization of components within the engine compartment. With less space and more temperature sensitive components, (plastics for lightweighting, infotainment, and electrical components) thermal management becomes an increasingly critical aspect of vehicle design. Component hot spots can lead to safety, durability, and warranty issues. Careful consideration of component placement and heat shields is mandatory to avoid costly late-stage fixes....

Advantages of Simulating Thermal Behavior of Underbody Components

Understanding the thermal behavior of underbody components can help an engineer balance the priorities and tightening restrictions for vehicle design. The underbody of a vehicle experiences some of the most thermally dramatic scenarios for which there is no simple solution. By using a method that provides accurate thermal predictions, engineers can assess a variety of design options early in the product development cycle. These predictions will provide a better understanding of the thermal behavior the vehicle will undergo under both extreme and common scenarios....

Introducing CoTherm: A Better, Faster, More Robust CAE Coupling Solution

You’re familiar with the expression, “You can have it fast, you can have it done well, or you can have it cheap…pick two.”? Well, thanks to a new tool currently in beta (with an early spring release date), CAE engineers will soon be able to choose all three....
