The 3 Pivotal Steps to Master Advanced Coupling

Finding the optimal solution to a design challenge almost always requires a complex coupling process. CoTherm, our coupling software, allows you to plan, control, and monitor multi-physics simulations for complex transient simulations like drive cycle scenarios. In order for advanced simulations to be worth your while, it is important to be familiar with the process and prerequisites so you can set yourself up for success. As we transition from discussing the importance of coupling as a whole to the necessity of accurate inputs, we will look at the specific things you must do well in CoTherm to get successful results from advanced simulations....

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....

How to Balance Accuracy and Efficiency: When to use Thermal Simulation, CFD or Both

Simulation software can be a valuable tool in the engineering process by allowing teams to simulate projects early on, enabling users to investigate the effects of various environments and design changes before expensive and labor-intensive prototyping processes....

8 Questions to Ask When Building Your Thermal Model

Thermal modeling can be particularly challenging because setting up your thermal simulation can be different every time. Meanwhile, you seek to balance competing priorities within your design. "It should be lightweight! Durable! Affordable!" the list of hopeful attributes is extensive so some compromise will have to occur. You can better decide where those accommodations can be made with an accurate thermal model. ...
