PreonLab 2.1 released

We are proud to announce the release of PreonLab 2.1. Some of the most prominent new features are:

• Improved PREON® Solver:: timestep criterion for viscosity forces and stopping criterion for the pressure solver
• Revised Plot Dialog: post-process statistics data before exporting them
• Enhanced Python library preonpy: full access to connections and keyframes
• Full preonpy API documentation: each function and every argument explained
• PreonLabCLI: simulate pre-processed scenes or run Python scripts
• Dynamic pathlines: see how particle traces evolve over time

This is just a small excerpt from the extensive feature list of PreonLab 2.1. Be sure to check the changelog for a complete overview.

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.

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.
