OpenLB Community YouTube Channel Update

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 create a new show case dealing with this topic: Nebulizer Simulation

The simulation was performed by Mathias J Krause using OpenLB
( 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.
