After only a short time, PreonLab's SPH code has already established itself at MAN Truck & Bus SE as a leading simulation tool for the development of new powertrains. PreonLab helps us to drive transmission train development forward with decisive impulses already in the early concept phase, thanks to extremely lean model preparation, fast simulation time, and high result quality. The software thus brings numerical flow calculation to a new level in the overall development process of complex powertrains.

For an optimal oil supply to the components in gearboxes, the shape of the housing and the internal flow processes play an important role. Using the PreonLab simulation software, it is possible to perform an analysis of the oil flow virtually. The simulations help us understand the flow in closed housings and help us save the cost of expensive, elaborately designed, transparent prototypes.

The body is probably the most multifaceted element of a vehicle. Largely responsible for the visual impression, it also provides protection against weather-related influences. In addition, it must be considered that where air flows, air noise is also generated. These noises can be perceived both around the vehicle and in the interior.
Electrified vehicles (EVs) are measured by their performance, range and cost. In addition, a compact powertrain design is desired, which has implications for thermal management.
The nearly silent operation of e-motors makes the vehicles quieter, but results in various noises and vibrations no longer being masked by the engine.
PreonLab 7.1 advances particle-based simulation with new airflow generation for soiling, enhanced vehicle dynamics, and more accurate, faster thermal simulations. Performance, fidelity, and usability are improved through efficiency gains and customer-driven workflow enhancements, enabling smoother, more intuitive simulation work.
This short article displays series of fun, water-inspired simulations that bring fluid motion to life. From crystal-clear pool ripples, cascading fountains, and waves, to energetic splashes and sprays, each simulation captures a different aspect of water in motion, all powered by particle-based fluid dynamics.
Tank sloshing occurs when liquid moves inside a container because of the interaction between the liquid’s free surface and the container walls due to external forces acting on the container. In the automotive industry this is commonly observed in fuel tanks or liquid transportation systems.
Preoneers know that PreonLab is all about particles! With each release we aim to continually add new functionalities and keep improving on existing capabilities, to make our goal of developing the ultimate simulation tool a reality. Accordingly, version 6.2 will bring many additions and updates to expand on the multiphysics capabilities of PreonLab.
Vehicle and sensor soiling is becoming an increasingly important aspect of vehicle design. The focus is clearly shifting from pure aesthetics to challenges related to safety improvement and cost reduction.
Vehicle water management is a critical component of design, which traditionally has heavily relied on costly physical testing. Whereas conventional CFD is hardly applicable due to underlying modeling complexity and extremely high computational costs, SPH technology has virtually revolutionized water management simulation.

Preoneers rely on the fact that with every new release, PreonLab aims to enhance your simulation experience by increasing efficiency and reducing the memory footprint for simulations. We firmly hold this at the core of our vision towards developing the ultimate simulation tool.
Every Preoneer knows that with PreonLab we always strive to provide the most reliable, usable
and efficient CFD software. But what if you could get your results even faster?
When it comes to complex production processes in the automotive industry like e-coating, using reliable CFD simulation tools to supplement expensive prototyping and physical testing has proven to be a very efficient method to optimize the design stag
Water management is an important aspect of vehicle design. It includes everything from soiling and wading to splashing and the impact this has on the vehicle's aerodynamics. Even the vehicle's windshield wipers are part of it, as is the investigation
Vehicle water management is a challenging engineering problem to address, but the right development tool can make the process more efficient and enjoyable for the engineer.
An important design task of gearbox development is the optimization of its lubrication across a wide range of operating conditions, lubricant viscosities, oil fill levels, vehicle grades and dynamic maneuvers.
Vehicle soiling phenomena can be a major safety hazard due to obstructed driver’s visibility of the road or abnormal operation of advanced driver assistance systems (ADAS).
