raditionally, water management design occurs late in
the vehicle development cycle, focusing on mitigation
rather than proactive development and requiring
expensive prototypes and testing facilities. These tests are
inherently chaotic, making it challenging to accurately observe,
measure, and replicate critical behaviors.
Conventional (mesh-based) simulation methods are often
Tractically inaTTlicaFle, or at Fest, too diƾcYlt and costly
to aTTly to JYll veLicle configYrations. 3n tLe otLer Land,
smoothed-particle hydrodynamics (SPH) simulation is an
emerging meshless CFD technology that excels in such large-
scale and highly dynamic cases.

featuring a distinctive meshless formulation with high-

capabilities.
PreonLab is designed for optimal performance, usability, and
reliability. It provides engineers with an all-in-one solution –
from model setup to rendering – allowing them to quickly
deliver clear and actionable visualizations to help shorten
development cycles.
The predictive capability of PreonLab has been validated
for the most relevant wading scenarios, showing excellent
agreement witL test data e.g., sYsTension deƽections and
resulting forces on underbody components). Over the past
few years, it has revolutionized water wading analysis and
has been successfully established throughout the automotive
industry as the market-leading SPH-based solution.
PreonLab provides a cost-effective solution to the numerous
challenges and complexities of designing vehicles to
withstand water-related issues, such as water ingress, vehicle
functionality and structural integrity, water tightness and
corrosion risk.

Vehicle water wading is one of the crucial aspects of vehicle design,
ensuring the functional and structural integrity of the vehicle in a variety
of real-world conditions (wading depths and vehicle entry speeds).
