Latest release

PreonLab 5.3 Released

PreonLab 5.3 is out now! It improves upon features from previous releases and adds some useful new features. As always, our focus is on improving reliability, performance, and usability.
Here are some of the highlights:

  • Pathlines: This release adds more options to accurately select and track fluid in regions of interest. This includes tracking particles passing by geometries in a specified time interval.
  • Airflow import: PreonLab 5.3 can better handle volumetric data saved to the Ensight Gold format and seamlessly integrates the airflow data into the simulation domain.
  • Thermodynamics: PreonLab 5.3 introduces a new heat capacity modifier, which enables thermal simulations with solids to reach equilibrium faster. This is handy for thermal applications where the results from the steady state are the focus of the analysis.
  • Usability & Workflow: Users can now track their action history for a single session and jump between two states with just a click of a button in the action log, which is a dedicated tab in the PreonLab GUI. This release also improves the plot dialog performance making it possible to consider an even larger amount of data for analysis than ever before.

We make engineering enjoyable


Shorten development cycles with PreonLab. Virtual prototyping has never been that easy and fast.


With our particle-based SPH approach, you get simulations with remarkable accuracy.


Increase your innovation potential with PreonLab, while saving resources, time, and costs.
The combined use of virtual prototyping using PreonLab and testing is an efficient approach in the development of lubrication and cooling concepts for e-axles. It efficiently supports us in achieving our goals in terms of functional design as early as possible.
