by Marc Gissler

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 3.0 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.

Meet us at the AVL International Simulation Conference 2017

June 9, 2017June 9, 2017
by Jens Cornelis

FIFTY2 will be attending the AVL International Simulation Conference 2017. We cordially invite you to join us on June 27-29, 2017 in Graz, Austria. We will be part of the exhibition and we are happy that Daniel Wickert from TU Dresden (Institut für Kraftfahrzeugtechnik) will present the results of a benchmark sponsored by Daimler AG considering “Water path prediction in the automotive industry” that included PreonLab outperforming the competition.

The three day conference will revolve around the latest simulation methodologies applied to key development goals for clean and affordable mobility, such as real-driving emissions, powertrain efficiency, electrification, durability and NVH.

You can gather more information on the program and of course register here:
