The PreonLab development team is pleased to announce the availability of new release the innovative software tool PreonLab 5.1 is packed with features that improve reliability, performance and usability across a wide range of applications.
Here are some of the highlights:
Faster Snow Solver:
The snow solver is a distinguishing feature of PreonLab. Every version since PreonLab 4.0 has continuously improved the snow solver but PreonLab 5.1 has the biggest direct effect: The implicit solver now converges much faster to a qualitatively equivalent solution. As a result computing times for scenes with chunks of snow are down by an astonishing factor of five. Simulating one physical second in the example for instance took us 8 hours whereas now it only takes an 1 hour and 40 minutes. So if you don’t like waiting, consider updating to PreonLab 5.1 as soon as possible!

Thermodynamics & Boundary Conditions:
With new boundary conditions, scenes can now be set up and initialized in more detail than ever before. Many quantities that could only be provided as constant values can now be initialized on a per-particle level with PreonLab 5.1.
Area sources and volume sources can now assign individual temperatures to every newly generated particle based on a connected point cloud resource. In a similar manner, it is now also possible to map heat flux profiles onto solid surfaces as thermal boundary conditions. In case of the area source, you can also use the point cloud resource to map initial speeds to the releasing particles. We also added a predefined pipeflow velocity profile for convenience.

Multiphase Simulation:
For many applications, single phase simulations are the best option to achieve good results quickly. In these cases, the contribution of other phases (typically air) is often modelled implicitly, for instance using PreonLab’s drag force object. However sometimes, the contribution of other phases is crucial and must be simulated explicitly to achieve meaningful results. With PreonLab 5.1, we have optimized multiphase to deliver better results for both low- and high-density contrasts. The quality of the simulation is improved using the new Continuum Surface Stress model which captures surface tension effects between the phases more accurately. To improve efficiency, we added the option to use different particle sizes for different phases. Additionally, it is also possible to use adaptive resolution for each phase. Last but not least we have developed best practices and workflows for some of the most common applications such as gearbox simulations.

Improved Adaptive Resolution:
Adaptive resolution refines or coarsens particles on the fly as they enter or leave regions of interest. Since PreonLab 5.0, you can use three resolution levels to concentrate the computational power on the region where accuracy counts while saving performance in less prominent regions of the simulation domain.
PreonLab 5.1 introduces several changes that make adaptive resolution even better. Firstly, overall performance has been improved by up to 20%. Secondly, it is now possible to refine particles in proximity to selected geometries in the scene. In many cases, this allows to refine more precisely only where it matters, which can greatly improve overall performance. Thirdly, adaptive resolution now supports multiphase simulations, pathlines, periodic boundary conditions and the solid volume solver. This means that more applications can now be accelerated with adaptive resolution.
In this e-coating example, the new proximity refinement is used to accelerate the simulation. Only the fluid close to the car surface is simulated in high resolution.

PreonLab is the disruptive innovation for CFD simulation. It focuses on simulating free-surface flow in highly dynamic simulation setups with minimal preprocessing effort. No meshing is required even for complex objects and kinematics. The software enables accurate prediction of the flow paths of water or oil helping to improve the design of components and integration into the whole vehicle. With PreonLab it is possible to create impressive animations of the simulation results.
The PreonLab 5.1 is packed with great new features that will help you to enjoy your daily work with PreonLab even more.
Founded in 2015 and headquartered in Freiburg, Germany, FIFTY2 is a constantly growing start-up and think tank for world class researchers and engineers. The first product, PreonLab, is a particle-based simulation software for free-surface fluids which is unique in its ease of use, high performance and visualization capabilities. PreonLab is productively used by more than 50 companies in 12 countries.
