We have released two new Videos on our OpenLB YouTube Channel. The first Video is about a 3D simulation of blood flowing through the human aorta. The second one visualizes phase separation in 3D.

In a collaboration of the Lattice Boltzmann Research Group (LBRG) at the Karlsruhe Institute of Technology (KIT) and the Institute of Reactive Flows and Diagnostics of the department of Mechanical Engineering at the Technical University of Darmstadt, the capabilities of two open source near-wall-modeled large eddy simulation (NWM-LES) approaches were investigated to predict complex turbulent flows relevant to internal combustion (IC) engines.
Therefore, OpenLB was compared to the commonly applied open source tool OpenFOAM, using a highly precise particle image velocimetry measurement as reference. The comparison covers prediction accuracy, computational costs and ease of use.
The performance results show that the OpenLB approach is on average 32 times faster than the OpenFOAM implementation for the tested configurations. The faster calculation speed for NWM-LES using the lattice Boltzmann method implementation in OpenLB is advantageous to address industrial applications and to enable “overnight” calculations that previously took weeks.

2020/03/13 | LBM Spring School with OpenLB Software Lab successfully finished. The executive committee announces the closing of the third LBM Spring School with OpenLB Software Lab. We were happy to host 60 participants from nine countries, including five invited speakers in Berlin, Germany. This year’s poster award goes to Dominik Wilde et al. from the University of Siegen, Germany.
Next year, the 5th spring school (https://www.openlb.net/spring-school-2021/) in planned to take place at the University of Greenwich in England/UK form 2021 May 31st to June 4th.

2019/12/11 | LBM Workshop with OpenLB Software Lab in Brazil Successfully Finished. The executive committee announces the closing of the LBM Workshop with OpenLB Software Lab at UFRGS in Porto Alegre, Brazil. We were happy to host 35 participants including five speakers from LBRG (KIT, Karlsruhe, Germany).
The workshop took place in the framework of the Brazilian-German PROBRAL project “Mesoscopic Molecular Dynamics Simulations: Development of Models and Computational Strategies for Complex Structural Bioinformatics Problems” supported by CAPES and DAAD.
On behalf of the workshop executive committee, Marcio Dorn, Mathias J. Krause, Stephan Simonis.
Registration is now open for the Fourth Spring School on Lattice Boltzmann Methods with OpenLB Software Lab that will be held in Berlin, Germany, from 9th to 13th of March 2020. The spring school introduces scientists and applicants from industry to the theory of LBM and trains them on practical problems. The first half of the week is dedicated to the theoretical fundamentals of LBM up to ongoing research on selected topics. Followed by mentored training on case studies using OpenLB in the second half, where the participants gain deep insights into LBM and its applications. This educational concept offers a comprehensive and personal guided approach to LBM. Participants also benefit from the knowledge exchange during the poster session, coffee breaks, and the excursion. We look forward to your participation.
Keep in mind that the number of participants is limited and that the registration follows a first come first serve principle.

Release 1.3.1 is now available for download. This Release includes some minor bug fixes:
We have just released a new Video on our OpenLB YouTube Channel. The Video shows the simulation of a nebulizer which is used to deliver small droplets of medical drugs through the patients lungs.
For further information we created a new show case dealing with this topic: Nebulizer Simulation
The simulation was performed by Mathias J Krause using OpenLB
(www.openlb.net). The Video was created by Alexandra Kerl.
If you have a nice video which you have obtained with OpenLB, please let us know and we will link it or upload it. Please contact us.
Release 1.3 Available. The OpenLB developer team is very happy to announce that a new release of the open source Lattice Boltzmann Method (LBM) code is available for download as well as a new doxygen documentation. Have a look and be excited!
OpenMPI 1.8 and higher, Intel MPI 5.0 and higher
PS: Please consider joining the developer team, by contributing your code and strengthen the LB community by sharing your research in an open and reproducible way! Feel free to contact us here: Contact
How to constantly clean paint from iron particles?
In the painting lines in the automotive industry, iron particles that reside in paint of a previous production step like tiny welding beads can lead to optical errors in the lacquering of cars. To prevent problems caused by these inclusions, magnetic separators are used to continuously remove the metallic particles from the liquid paint.
Inside the magnetic separator, a static magnetic field is generated by permanent magnets. The magnetic forces attract the metallic particles towards the inner cylinder wall while the remaining liquid flows through and finally leaves the separator.
Here you can find more Information about Magnetic Separation.
