The automotive world is changing. In order to keep up with the challenges faced in the context of digitalization, Audi established the simulation of water in the development process.
2019 has been an extraordinary year for PreonLab. Probably the most exciting part was seeing the results that you achieved in your respective fields. Let’s push the boundaries of simulation further in 2020!
We’re kicking off the new year with the release of PreonLab 4.1, which expands and improves the features introduced in 4.0. The most notable changes include:
- Improved local refinement: Local refinement is no longer an experimental feature and is now available for all users.
- Preonpy sensor interface: It is now possible to access per-sample sensor data in preonpy, which allows for more powerful and customized post-processing.
- Improved property editor: With physical units everywhere, better keyframing integration and many fixes, PreonLab 4.1 delivers a more reliable and productive user experience.
- Improved snow solver: The snow solver is now more robust and efficient.
PreonLab is successfully employed by Renault to validate and improve heat shield designs which guarantee that no flammable liquid gets in contact with hot parts of the engine. Testing on a real prototype is difficult since first the leakage itself has to be reproduced and secondly, hot liquids may be dangerous.
Thanks to the electrification of the powertrain, innovation in the automotive industry is happening faster than ever. Short time to market for electric vehicles (EVs) and hybrid vehicles (HEVs) is one key to be successful for OEMs and tier 1 suppliers.
These are challenging and exciting times for the automotive industry. In 2020 the current EU regulations that set CO2 emissions standards for cars and vans will be replaced with stricter targets to be met by 2025, so innovative solutions are necessary to secure high mobility comfort at low emission rates. Our customer Volvo Car Corporation aims to have 50% of their annual sales come from fully electric vehicles.
Our customer Merkle & Partner expressed a great compliment about PreonLab in the German journal ‘Konstruktion & Entwicklung’. With our simulation software PreonLab “an evolutionary leap could be achieved compared to conventional CFD methods”, states Merkle & Partner. By adding our software to their simulation toolbox ‘Merkle & Partner Öl-Sim’, the company now receives the requested results after a brief period of time.
We are very excited to announce the release of PreonLab 4.0. This major release expands, improves, and accelerates the core capabilities of PreonLab, highlighted by the following features:
- Snow solver: PreonLab continues to push the boundaries of particle-based simulations with the introduction of a semi-implicit snow solver.
- More accurate fluid solver: The updated Preon solver is able to capture even more phenomena and requires less parameter calibration.
- Implicit thermodynamics solver: The thermodynamics solver now supports much larger timesteps via implicit integration, greatly improving performance.
- Local fluid refinement (experimental): It is now possible to use two particle sizes in the same simulation, reducing computation time and the amount of generated particle data.
FIFTY2 keeps thriving. It took only three years to grow out of our second office. We are happy to announce that we moved into a much bigger office, staying in our home town Freiburg, located in the beautiful Black Forest.
Our new rooms are giving us the opportunity to work even more efficiently, as we are looking forward to releasing PreonLab 4.0 later this month!
PreonLab 3.3 represents the final 3.x release and we are very excited to share it with you. Here is a selection of the most notable new features and improvements:
- Non-Newtonian fluids: For the first time, the Preon Solver supports the simulation of non-Newtonian fluids.
- Improved car suspension model: The improved car suspension model now simulates vehicle suspension due to fluid interaction more accurately and supports user-defined spring constants.
- Improved efficiency: PreonLab 3.3 includes an optimized geometry handling that improves performance, cuts down loading times and reduces memory consumption
- “Experimental” mode: The experimental mode exposes selected features currently in development to all users who wish to try them out
