PreonLab 3.1 released

We are proud to anounce the release of PreonLab 3.1. Without further ado, here is why you want to update to PreonLab 3.1 as soon as possible:

• New viscosity model: The new default viscosity model combines the strengths of the different previous models into one and delivers realistic results on all resolution scales.
• New rigid body solver: The new experimental solver brings key ideas behind the PREON fluid solver to rigid body dynamics.
• Improved renderer: Preon renderer now supports a wide range of materials like steel, rubber or glass.
• Improved thermodynamics solver: Added MPI support, resolution-independent diffusion model and better free-surface handling.
• Improved usability: PreonLab has never been more fun to use.

Please note that with PreonLab 3.1, we have updated our toolchain and now provide unified binaries for Linux distributions.

PreonLab 3.0 released

PreonLab 3.0 released

Three years ago, FIFTY2 was founded under the premise to bring the revolutionary PREON® fluid solver from university to industry. Today, this dream has become reality – PreonLab has found adoption by engineers around the world. Now, it is time to look ahead and open up PreonLab for more applications. PreonLab 3.0 is by far the most transformative update yet and we couldn’t be more excited to share it with you.

An extract from the extensive list of new features in PreonLab 3.0:

• Distributed computation: PreonLab becomes MPI capable – use clusters for even faster simulation results.
• Additional simulation capability: add thermodynamics and evaporation models to your simulation.
• Improved water wading simulation: increased reliability by taking into account the vehicle suspension.
• Improved workflow: an entirely redesigned Playback and Simulation control and improved connection editor improves the workflow.

PreonLab 1.4 released

PreonLab 1.4 provides a batch of usability improvements and additional features such as:

• Improved Connection Editor for a simplified and quicker simulation setup
• Revised Keyframe Editor for more efficiency and precision in setting up the kinematics
• Introduction of a separate simulation and view frame rate for, e.g., versatile post-processing
• Archive function for sparse data storage
• Integration of FFmpeg enables rapid video export from within PreonLab
• Liu drag force model introduces an improved droplet behavior without the need for parameter tuning

PreonLab 1.3 released

PreonLab 1.3 comes with an enriched and optimized feature-set for pre- and post-processing. The improved camera and the extended clipping objects make navigating in the 3d scene much easier. Pre-processing is simplified by resource objects which can hold animations provided in vda file format or manage multiple meshes stored in one file. Furthermore, an alternative sampling method is introduced which is independent of the triangle mesh structure. This prevents leakage for high-poly meshes. Post-processing capabilities are extended by motion-aware pathlines as well as the Preon renderer which now supports wetting and force sensors. Read more “PreonLab 1.3 released” →

PreonLab 1.2 released

PreonLab 1.2 comes with an impressive feature set and significant improvements in the physics core of PREON®. Visualization is an important, yet often neglected component of physical simulation. PreonLab 1.2 enables the engineer to create impressive presentations of the simulation results using Preon renderer and the brand new material presets. Version 1.2 additionally features usability improvements, such as a distance measuring tool which comes in handy during scene setup and post-processing.
