Lattice-Boltzmann methods in fluid dynamics: Turbulence and complex colloidal fluids

First benchmarks of LB3D with additional timing functions performed during the workshop showed that the coupling of suspended particles to the fluid involved a subroutine that scaled linearly with the number of cores. Due to the small pre-factor this was not recognized earlier. Another finding was that the (serial) output of the Lagrangian particle trajectories would fail for large core counts since it relied on point-to-point communication between every rank.
