Ensuring wet weather performance while a vehicle is traveling on the highway is crucial to driver safety and vehicle reliability. Being able to account for water clearance under various conditions while a design is still in the digital phase is possible with our solution’s 3D CFD tools. Our solution enables you to ensure that a vehicle performs in wet weather to the exacting standards you expect.

Water Management Solutions for Automotive Performance Engineering
A complete understanding of how a vehicle interacts with water, either rain or standing water, is an issue of safety, reliability and quality. It directly affects a driver when most critical – in a rain storm on a highway at high speed.
Aspects beyond wiper blade performance must be considered. Drainage performance must ensure that water is cleared quickly and does not accumulate near electronic equipment, that wading through puddles does not cause water ingestion by the engine intake system or damage underbody trays. Side window visibility involves the complex interaction of water and the flow from the A-pillar and wing mirror.
Our solution allows you to directly model these considerations and more with a complete 3D CFD solution that accounts for multiphase flows such as liquid films, sprays and deposition. Forces generated by water on structural components can be investigated by fluid-structure interaction where the external flow and internal solid stresses are solved concurrently. Using our solution you will be able to digitally investigate all of these phenomena early in the design to ensure the driver of wet weather safety and performance.
Cover multiple flow regimes in a single simulation
Real-world applications often contain more than one flow regime, from droplets to sprays and thin films. These applications were traditionally studied using multiphase models incapable of capturing many important features. Recent developments in technology allow several multiphase models to work together and extend the applicability of some traditional models so that they can cover multiple regimes in a single simulation.
This webinar demonstrates how, with advances in hybrid multiphase modeling, compromises are becoming a thing of the past.
Designing under-body components using leading wading simulation methods
Wade testing involves vehicles being driven through different depths of water at various speeds. The test is repeated and under-body functional parts are inspected afterwards for damage/leakage. A lack of computer aided engineering (CAE) capability for wading results in late detection of failure modes, which inevitably leads to expensive design change that can affect program timing.
FSI simulations in the automotive industry
Driving through puddles or wading through water causes water to be splashed toward the bottom of the vehicle. This water can cause problems with the contamination of components or, in the worst case, break them.
The purpose of this study was to evaluate the structural integrity of components where the long-term goal was to prevent structural failure. The study was performed by analyzing, among else structural stresses and thereby monitoring components with high risk of breaking due to the splashing phenomena. Eventually, a virtual method within fluid-structure interaction (FSI) was developed for VCC.
