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.
New boundary handling
The boundary handling in PreonLab 1.2 has been substantially improved. The new boundary handling in PREON® does not rely on a simplified, symmetric condition, but computes dedicated pressure values for the boundary. This especially yields in more precise results in scenarios with a closed domain, e.g., a lid driven cavity.
However, the old boundary handling still offers a fast alternative to the new one and is still supported. Both approaches will co-exist in the future.
Material presets for Preon renderer
A promotional presentation of the simulation results is necessary in some cases. Preon renderer makes it possible to create impressive renderings of the simulation data right within PreonLab. With PreonLab 1.2 we introduce material properties to Preon renderer, e.g. water presets. This makes it possible to create photorealistic video material with PreonLab and presenting simulation results in a new fashion.

Improve performance using boundary conditions
In PreonLab 1.1 we introduced boundary conditions that define a fluid velocity inside a user-specified volume. In PreonLab 1.2, we optimized the solver so that fluid inside a scripted region is handled very efficiently. This allows to boost performance in scenes where only selected areas of the fluid simulation are really of interest. One of the best examples for this is a wading simulation in which only the water around the car really matters for the simulation result. With the optimized boundary domains, it is now possible to script passive water on the road efficiently. The featured water wading simulation has been computed accordingly, boosting the performance by a factor of over 2.0 while reducing the memory consumption.
As always, check out the changelog for a full list of changes. To learn more about the new features, have a look at the updated manual. We hope that you will enjoy working with PreonLab 1.2 and as always, we appreciate your feedback.
