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 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 2.0 Released

We are proud to announce the release of PreonLab 2.0. Some of the most prominent new features are:

• PairwiseForce model for cohesion, adhesion and roughness
  (calibrated and validated by the TU Dresden).
• PreonLab boundary handling: with the ‘no gap’ option, the offset between fluid and boundary is eliminated.
• Python library ‘preonpy’: the power of PreonLab at your hands right from your own python scripts.
• Velocity keyframing for even more intuitive and easily accessible rigid kinematics.
• Extended file format support: export your fluid data to the Ensight file format.

This is just a small excerpt from the extensive feature list of PreonLab 2.0. Be sure to check the changelog for a complete overview of the impressive changes.
