Article: PreonLab as an evolutionary leap

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.

PreonLab 4.0 Released

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.

PreonLab 3.3 Released

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

PreonLab 3.2 Released

PreonLab 3.2 is here! Besides numerous smaller improvements, this release also includes major innovations that open up new applications and new workflows:

• Implicit viscosity solver: The new (optional) solver is capable of simulating highly viscous fluids at large timesteps and superior performance.
• Optimized post-processing: PreonLab 3.2 greatly reduces the system requirements for post-processing and improves overall responsiveness of the user interface for large scenes.
• Keyframe spline interpolation: The new interpolation method significantly reduces the effort to generate smooth interpolation between keyframes and makes defining kinematics even easier than before.
• Unified Area source with cone support: All two-dimensional fluid sources are now unified into one. The new versatile Area source also introduces a conical emission shape.

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.
