Fluid flow from a hose under gravity

Author: Claas Bierwisch
The movie shows a fluid in a rigid pipe which is connected to a hose of rubber-like material. A piston moves towards the left through the pipe thereby pushing the fluid out of the hose. Gravity is accelerating the fluid downwards. ... more

Discrete and finite element co-simulation

Author: Claas Bierwisch
The possibility of coupling discrete element method (DEM) and finite element analysis (FEA) simulations is particularly attractive in order to model contact between granular matter and soft bodies. The coupling takes place at the ... more

SPH simulation of a particle impact on a ductile target

Author: Christian Nutto
The sequence shows an impacting body on a ductile target made of Al6061-T1. The impacting body is assumed to be ideally hard. The impact velocity is $45 \mathrm{m/s}$ and is tilted $51^°$ from the horizontal axis. The spacing of ... more

Sweeping granular matter with a flexible lamella

Author: Claas Bierwisch
The movie shows lamellas of different flexibility which are used to sweep cohesive granular matter by a lateral movement. The effectivity of the sweeping depends strongly on the rigidity of the lamella. Cleaning processes are appl ... more

Drying drop on a substrate: The coffee stain effect

Author: Thomas Breinlinger
This video shows the drying of a silver ink micro droplet on a solid substrates. The simulation is carried out using the discrete element method (DEM) which is combined with an analytic solution of the fluid motion via one-way-cou ... more
